Abstract:

The presence of large peatland in Riau, Indonesia, could cause air pollution due to peatland fires which causes the presence of thick smoke every year in Riau, dis-rupting human activities. In order to monitor the air quality, in this paper, the main advantage of the Internet of Things (IoT) is the ability to transfer data over the network without requiring human-to-human or human interaction to the com-puter used. In this paper, we propose an air quality monitor that can display web-based information to show the temperature and air humidity, and detects CO, CO2 gases, and alcohol in real time with the help of DHT11 and MQ135 sensors, Arduino Uno and Raspberry Pie. The results show our proposed system can successfully show each parameter of the air quality on the website and make suggestions about the overall air quality level. With our proposed system, we hope the government can respond faster to mitigate the bad air quality level and give information to public about the air quality level in a faster and more accurate way.

Abstract:

Much after more than many years of information gadgets advancement, numerous individuals despite everything discover the association with the PCs and robots an awkward encounter. Endeavours ought to be made to adjust PCs and robots to our regular methods for correspondence: discourse and non-verbal communication. The point of this work is to actualize an ongoing order framework through hand movement affirmation, using all around helpful gear and low costing sensor like a direct raspberry-pie and a USB webcam, so any customer can use it in organizations or at home. The reason of our philosophy is a fast division method to procure the hand movement from the whole picture which can oversee immense number of hand shapes against different establishments and lightning conditions, and an affirmation method that recognizes the hand pose for various control application. Administration robots legitimately associate with individuals, so finding an increasingly common and simple UI is of crucial significance. While prior works have concentrated principally on issues, for example, control and route in the earth, scarcely any automated frameworks are utilized with straightforward interfaces that can control the robot by trademark techniques. This energize response need. In this method, customer will handle the robot by using movements with palm. Here request indications were delivered for the movements using picture getting ready, where gaussian blur algorithm is used to reduce noise in the image, Canny-edge algorithm is used to detect fire out-layers and masking algorithm is used for Ro extraction.

Abstract:

Raspberry is a valuable berry crop containing a large amount of antioxidants that correlates with the color of the berries. We evaluated the genetic diversity of differently colored raspberry cultivars by the microsatellite markers developed using the flavonoid biosynthesis structural and regulatory genes. Among nine tested markers, seven were polymorphic. In total, 26 alleles were found at seven loci in 19 red (Rubus idaeus L.) and two black (R. occidentalis L.) raspberry cultivars. The most polymorphic marker was RiMY01 located in the MYB10 transcription factor intron region. Its polymorphic information content (PIC) equalled 0.82. The RiG001 marker that previously failed to amplify in blackberry also failed in black raspberry. The raspberry cultivar clustering in the UPGMA dendrogram was unrelated to geographical and genetic origin, but significantly correlated with the color of berries. The black raspberry cultivars had a higher homozygosity and clustered separately from other cultivars, while at the same time they differed from each other. In addition, some of the raspberry cultivars with a yellow-orange color of berries formed a separate cluster. This suggests that there may be not a single genetic mechanism for the formation of yellow-orange berries. The data obtained can be used prospectively in future breeding programs to improve the nutritional qualities of raspberry fruits.

Abstract:

The increased usage of wireless communication has created a wireless frequency shortage problem. Cognitive Radio (CR) has attracted public attention, as one of the solutions that can resolve this issue. In this paper, the authors built an actual CR system testbed using the SDR (Software Defined Radio) platform, USRP (Universal Software Radio Peripheral) board, the SDR development toolkit, GNU Radio, and Raspberry Pi3, which is a single board computer. They configured Secondary User (SU)s with Raspberry Pi3 for straightforward and portable test environment. The authors' testbed performs spectrum sensing based on energy detection and determines whether the channel is occupied or not. Experimental results not only show performance but also provide their testbed that works well in multi-hop environments.

Abstract:

Red raspberry production in the western United States is heavily reliant on preplant soil fumigation to ensure the successful establishment and productivity of a planting. However, due to issues related to the regulation, availability, and economics of soil fumigation, alternatives are needed for current fumigation practices. Trials were conducted in commercial raspberry fields in California and Washington to evaluate alternatives to current fumigation practices in each region. In Washington, tarped bed fumigation with 1,3-dichlorpropene (1,3-D):chloropicrin (Telone C-35) performed as well as, and sometimes better than, the industry standard nontarped broadcast fumigation with Telone C-35 for the control of the soilborne pathogen Phytophthora rubi and the plant-parasitic nematode Pratylenchus penetrans. In one of the Washington trials, yield of raspberry grown in tarped bed-fumigated areas was 47% greater than the yield of plants grown in nontarped broadcast-fumigated areas. In California, a combination of chloropicrin:1,3-D (Pic-Clor 60) performed as well as the industry standard of methyl bromide:chloropicrin. Raspberry plants grown in soil fumigated with either of these fumigants were approximately 26% taller than plants grown in nonfumigated soil. Our results indicate that there are viable fumigation alternatives to the current fumigation systems used in Washington and California raspberry production systems.

Abstract:

В настоящее время к одним из наиболее приоритетных направлений пищевой промышленности относят разработку функциональных продуктов питания на основе экологически чистого сырья естественного происхождения, в том числе ягодного. При разработке новых продуктов с защитными свойствами важно учитывать ингредиентный состав сырья, оказывающий лечебно-профилактический эффект, и с этой точки зрения ягоды малины и брусники заслуживают особого внимания. С целью максимального извлечения и сохранения природных, физиологически-функциональных компонентов дикорастущих ягод (витаминов, микро- и макроэлементов, фенольных, пектиновых соединений и др.) были разработаны и созданы мультиэнзимные композиции для предобработки ягод брусники (МЭКб) и малины (МЭКм). Большой интерес вызывали исследования состава и содержания красящих веществ в исследуемых образцах. В качестве структурных элементов антоцианов в соке малины и брусники, а также в их ферментативных соках установлены дисахариды, основной структурный компонент которых - цианидин. Количественное содержание антоцианов в соке брусники и малины составило 305,4 и 106,2 мг/дм3, а в ферментативном соке брусники (БФС) и малины (МФС) - 553,7 и 146,4 мг/дм3, соответственно. Высокое содержание красящих веществ - важный критерий для использования БФС и МФС в качестве источника натуральных красителей. Установлена более высокая антиоксидантная активность в БФС и МФС (соответственно в 1,3 и 1,5 раза) по сравнению с соком, полученным без применения ферментных препаратов. Следовательно, ферментативный сок ягод обладает высокими антиоксидантными свойствами и служит источником натуральных красителей, поэтому его можно рассматривать как перспективный сырьевой полуфабрикат при производстве продуктов питания функциональной направленности, оказывающих благотворное регулирующее действие на организм человека. Currently, one of the priority areas of the food industry is the development of functional food products based on environmentally friendly raw materials of natural origin, including berry. When developing new products with protective properties, it is important to take into account the ingredient composition of the raw materials, which has a therapeutic and prophylactic effect, and from this point of view, raspberries and lingonberries deserve special attention. In order to maximize the preservation and extraction of natural, physiologically functional components of wild berries (vitamins, micro - and macroelements, phenolic compounds, pectin and other substances) were developed and created multienzymatic compositions for the pretreatment of lingonberry (MEKb) and raspberry (MEKm). Of great interest were studies on the characterization and content of dyes in the samples being studied. As structural elements of anthocyanins in raspberry and lingonberry juice, as well as in their enzymatic juices, disaccharides were established, the main structural component of which is cyanidine, and the quantitative content of anthocyanins (mg/dm3) in the juice of lingonberry and raspberry, corresponded - 305.40 and 106.20, and in the enzymatic juice of lingonberry and raspberry - 553.70 and 146.40. The high content of dyes is an important criterion for the use of BFS and MFS as a source of natural dyes. A higher antioxidant activity was found in BFS and MFS (1.3 and 1.5 times, respectively) compared with juice obtained without the use of enzyme preparations. Therefore, the enzymatic juice of berries has high antioxidant properties and is a source of natural dyes, so it can be considered as a promising raw material in the production of functional foods that have a beneficial regulatory effect on the human body.

Abstract:

To investigate phytonutrient accumulation in black raspberries, fruits of `Jewel' and `MacBlack' were harvested at stages from the onset of color development (S1) to ripe fruit (S7). S1–S7 samples were characterized for color reflectance and then frozen at –28 °C within an hour of harvest. Additional ripe fruit were maintained at 20 °C for 3 days to overripen (S8) before freezing. After storage, samples were analyzed for dry weight (DW), total soluble solids (TSS), fructose (FRU), glucose (GLU), and organic acid (ORG) contents; total phenolic (PHE) and anthocyanin (ACY) contents; individual cyanidin glycoside levels (ICG); and antioxidant capacity (FRAP and ABTS) by standard methodology. `Jewel' and `MacBlack' ripened similarly. Chroma values and DW percentage decreased while TSS levels, sugar contents (FRU+GLU), PHE, ACY, the ACY: PHE ratio, and ICG increased with progressive ripening stages (S1–S7). Values of PHE, ACY, and ICG were highly correlated (r < +0.95) with FRAP and ABTS values. ACY levels in S6 fruit were 18% to 23% less than those of S7; lower S6 ACY levels were associated with reduced antioxidant capacity in `MacBlack', but not `Jewel'. Overripened fruit (S8) exhibited increased DW (11% to 25%) and decreased sugar contents (16% to 17%), consistent with moisture and respiratory losses after harvest. After correction for these losses, S7 and S8 levels of PHE, ACY, FRAP, and ABTS were similar in `MacBlack'. However, as `Jewel' overripened, ACY levels and antioxidant activity increased 44% and 22% to 26%, respectively. Our data suggests that significant changes in the antioxidant behavior of black raspberries can occur during the periods surrounding peak ripeness.

Abstract:

This study focuses on the development of biocompatible oil-in-water (O/W) nanoemulsions based on polyglycerol esters, as promising carriers for natural actives: red raspberry seed oil—RO and hydro-glycolic fruit extracts from red raspberry—RE and French oak—FE. Nanoemulsions were obtained via phase inversion composition (PIC) method at room temperature by dilution of microemulsion phase, confirmed by visual appearance, percentage of transmittance, microscopic, rheological and differential scanning calorimetry (DSC) investigations. The results have shown that the basic RO-loaded formulation could be further enriched with hydro-glycolic fruit extracts from red raspberry or French oak, while keeping a semi-transparent appearance due to the fine droplet size (Z-ave: 50 to 70 nm, PDI value ≤ 0.1). The highest antioxidant activity (~92% inhibition of the DPPH radical) was achieved in the formulation containing both lipophilic (RO) and hydrophilic antioxidants (FE), due to their synergistic effect. The nanoemulsion carrier significantly increased the selective cytotoxic effect of RO towards malignant melanoma (Fem-X) cells, compared to normal human keratinocytes (HaCaT). In vivo study on human volunteers showed satisfactory safety profiles and significant improvement in skin hydration during 2 h after application for all nanoemulsions. Therefore, polyglycerol ester-based nanoemulsions can be promoted as effective carriers for red raspberry seed oil and/or hydro-glycolic fruit extracts in topical formulations intended for skin protection and hydration.

Abstract:

Light emitting diodes (LEDs) as an efficient low-consumption lighting technology are being used increasingly in many applications. The move to LED lighting is also changing the way the lighting control systems are designed. Currently, most electronic ballasts and other digital lighting devices implement the Digital Addressable Lighting Interface (DALI) standard. This paper presents a low-cost, low-power effective DALI LED driver controller, based on open-source Raspberry Pi3 microcontroller prototyping platform. The control software is developed as a Linux kernel module under UBUNTU 18.04.2 LTS patched with PREEMPT_RT (Preemptive Real-time) for real-time processing. This dynamically loaded kernel module performs all the processing, communication and control operations of the Raspberry Pi3-based DALI controller with the DALI LED driver and LED luminaire. Software applications written in C and Python were developed for performance testing purposes. The experimental results showed that the proposed system could efficiently and effectively manage DALI LED drivers and perform lighting operations (e.g. dimming). The system can be used for a variety of purposes from personal lighting control needs and experimental research in control of electronic ballasts and other control gears, devices and sensors, to advanced requirements in professional buildings, including energy management, lighting maintenance and usage.

Abstract:

In residential energy management (REM), Time of Use (ToU) of devices scheduling based on user-defined preferences is an essential task performed by the home energy management controller. This paper devised a robust REM technique capable of monitoring and controlling residential loads within a smart home. In this paper, a new distributed multi-agent framework based on the cloud layer computing architecture is developed for real-time microgrid economic dispatch and monitoring. In this paper the grey wolf optimizer (GWO), artificial bee colony (ABC) optimization algorithm-based Time of Use (ToU) pricing model is proposed to define the rates for shoulder-peak and on-peak hours. The results illustrate the effectiveness of the proposed the grey wolf optimizer (GWO), artificial bee colony (ABC) optimization algorithm based ToU pricing scheme. A Raspberry Pi3 based model of a well-known test grid topology is modified to support real-time communication with open-source IoE platform Node-Red used for cloud computing. Two levels communication system connects microgrid system, implemented in Raspberry Pi3, to cloud server. The local communication level utilizes IP/TCP and MQTT is used as a protocol for global communication level. The results demonstrate and validate the effectiveness of the proposed technique, as well as the capability to track the changes of load with the interactions in real-time and the fast convergence rate.

Abstract:

With the rapid technological development, the growing number of Internet clients over time, the internet access response is slow and it takes filtering of a few websites that can harm users. For that required cache proxy server to speed up internet access time and website filtering. The use of proxy servers usually still use the standard configuration on the proxy server. This configuration can be set or modified (tuning) in such a way as to create a proxy server that is reliable and have better performance. The play on the proxy server is done by changing some parameters that are inside the proxy server application and adapted to the needs of usage on the internet network. The application used to create this proxy server is squid that runs on raspberry pi3 with a rasbian operating system. Squid applications are mostly used in local and internet networks for storing web cache, blocking multiple websites, managing bandwidth up to access restrictions.

Abstract:

Rubus idaeus has remarkable economic and cultural value. Developing efficient simple sequence repeat (SSR) markers is necessary for the molecular breeding of red raspberry. In this study, SSR mining was performed using the de novo transcriptome sequence of R. idaeus. In total, 14,210 SSR sequences were identified from 11,158 SSR-containing unigenes. In all the SSR sequences, mononucleotide, dinucleotide, and trinucleotide repeats were the most common, and their number and percentage were 1323 (9.31%), 6752 (47.52%), and 4897 (34.46%), respectively. Of the mononucleotide and dinucleotide repeats, A/T, AG/CT, AT/AT, and AC/GT were more abundant and accounted for 9.09%, 37.82%, 6.51%, and 3.14% of the total repeat number, respectively. In the trinucleotide, tetranucleotide, pentanucleotide, and hexanucleotide repeats, the nucleotide (NT) patterns AAG/CTT, AAAG/CTTT, AAAAG/CTTTT, and AAGAGG/CCTCTT were the most frequent, and accounted for 14.11%, 0.38%, 0.57%, and 0.23% of the total SSRs, respectively. Of the 480 SSR-containing unigenes with gene ontology (GO) annotation, the classification results showed that they were mainly involved in binding, catalytic, and transporter molecular functions. Most of the 3441 SSR-containing unigenes with the Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation were involved in the following top five pathways: metabolic, RNA transport, spliceosome, protein processing in the endoplasmic reticulum, and mRNA surveillance. Thirty pairs of primers derived from the red raspberry transcriptome were randomly selected to assess their polymorphism by using 15 red raspberry germplasms, in which the polymorphism information content (PIC) values ranged from 0.50 to 0.86, with a mean of 0.73, thereby indicating a high level of polymorphism. The unweighted pair group method with arithmetic mean clustering results indicated that the thirty pairs of primers could precisely distinguish the germplasms. This study reveals the SSR distribution characteristics of red raspberry and provides a scientific basis for further genetic diversity studies and genetic linkage map construction for this species.

Abstract:

Circuit Board (PCB) is a micro-board containing various components electronics used in an automatic circuit. In PCB drilling is usually done human which takes a lot}when the hole in the PCB is getting more and more. And it takes precision when the eye touches the PCB board which gives rise to friction force and can cause drilling. The purpose of this research was the development of tools in the form of automated drills using computers with BCNC software as face-to-face CNC movements. The engine is driven with stepper motor and dc motor as spindle. In this BCNC software the drilling process is done by entering the codes in the form of gcode which can later be read by CNC. The coordinates of the holes in the layout that have been created are obtained by converting the layout into codes called gcode. The process is carried out using PCB designer software. Thoroughness testing on all six axes found an error 1,2% with ten attempts each. PID implementation on DC motor obtained constant value Kp = 54, Ki = 38 and Kd = 0.9. As well as before drilling, the installation of drill bits must be precise so that at the time of spinning, the drill bits do not shake.

Abstract:

This paper presents a performance evaluation of the development of the instrumentation, communications and control systems of a two-tank process by using low-cost hardware and open source software. The hardware used for automating this process consists of embedded platforms (Arduino and Raspberry Pi) integrated into programmable logic controllers (PLCs), which are connected to a supervisory control and data acquisition (SCADA) system implemented with an open source Industrial Internet of Things (IIoT) platform. The main purpose of the proposed approach is to evaluate low-cost automation solutions (hardware and software) within the framework of modern industry requirements in order to determine whether these technologies could be enabling factors of IIoT. The proposed control strategy for regulating tank levels combines the classic PID algorithm and the fuzzy gain scheduling PID (FGS-PID) approach. Fault detection capabilities are also enabled for the system through a fault detection and diagnosis module (FDD) implemented with an extended Kalman filter (EKF). The distributed controller’s (DC) algorithms are embedded into the PLC’s processors in order to demonstrate the flexibility of the proposed system. Additionally, a remote human to machine interface (HMI) is deployed through a web client of the IIoT application. Experimental results show the proper operation of the overall system.

Abstract:

Currently, we are in the digital era, where robotics, with the help of the Internet of Things (IoT), is exponentially advancing, and in the technology market we can find multiple devices for achieving these systems, such as the Raspberry Pi, Arduino, and so on. The use of these devices makes our work easier regarding processing information or controlling physical mechanisms, as some of these devices have microcontrollers or microprocessors. One of the main challenges in speed control applications is to make the decision to use a fuzzy logic control (FLC) system instead of a conventional controller system, such as a proportional integral (PI) or a proportional integral-derivative (PID). The main contribution of this paper is the design, integration, and comparative study of the use of these three types of controllers—FLC, PI, and PID—for the speed control of a robot built using the Lego Mindstorms EV3 kit. The root mean square error (RMSE) and the settling time were used as metrics to validate the performance of the speed control obtained with the controllers proposed in this paper.

Abstract:

Seiring dengan perkembangan teknologi komunikasi dan otomasi, pelaksanaan tugas militer dapat dibantu dengan mengembangkan alutsista militer. Salah satunya pengembangan robot tempur yang akan digunakan sebagai alat untuk membantu tugas operasi jarak jauh pada satuan tempur TNI AD. Pada robot tempur tersebut akan ditanamkan sistem komunikasi data berupa perintah kendali laju robot, perintah kendali senjata serang, dan sistem visualisasi yang dapat digunakan untuk mendukung pergerakan robot hingga mencapai sasaran yang ditentukan, serta sebagai sistem penginderaan jarak jauh robot tempur untuk memonitor area musuh yang akan ditinjau. Operator menggunakan sebuah joystick untuk mengendalikan robot tempur dan tablet Android untuk memantau dan mendeteksi arah sasaran. Penelitian ini membahas tentang perancangan pendeteksian sasaran tembak yang dapat dikendalikan dari jarak jauh. Metode yang digunakan adalah metode eksperimen berbasis PID. Penelitian ini berfokus pada pendeteksian sasaran tembak yang nantinya akan terhubung dengan Raspberry Pi 3, sehingga senjata dapat mendeteksi adanya sasaran tembak yang ada di dalam jangkauan sensor posisi. Hasil dari penelitian menunjukkan bahwa robot dapat dikendalikan dengan mudah menggunakan joystick dan secara real-time terlihat pada layar Android yang terpasang pada kontrol joystick tersebut. Selain itu, sistem juga dapat membedakan antara sasaran tembak dan objek yang bukan sasaran tembak. Penelitian ini diharapkan dapat mendukung tugas operasi personel TNI dalam menjalankan misinya dengan memanfaatkan robot tempur. Along with the development of communication and automation technology, the implementation of military duties can be assisted by developing military defense equipment. One of them is the development of a combat robot that will be used as a tool to assist the task of long-distance operations on the Army combat unit. In the combat robot, a data communication system will be implanted in the form of a robot rate control command, an attack weapon control command, and a visualization system that is used to support the robot's movement to reach the target specified as a combat robot's remote sensing system for monitoring enemy areas to be reviewed. The operator has used a joystick to control the combat robot and to detect the direction of the target can be monitored with an android tablet. This research discusses the design of the detection of target fire that can be controlled remotely. The method used is experimental based on PID. This research focused on detecting firing targets that will be connected with Raspberry Pi 3 so that the weapon can detect the presence of firing targets within the position sensor. The results of the research show that the robot can be easily controlled using a Joystick and in real-time visible on the Android screen mounted on the Joystick control, the system can distinguish between target shooting and non-target objects. This research is expected to support the operational duties of army personnel in carrying out their missions by utilizing combat robots.

Sampah merupakan hal yang tidak asing lagi bagi manusia saat ini. Bagi orang-orang yang tidak bertanggung jawab akan berfikir bahwa sampah dapat dibuang dimana saja, bahkan ada yang meletakkan sampah dengan mudahnya sambil meninggalkan sampah tersebut secara sembarangan tanpa berpikir bahwa ada tempat sampah yang layak dan sesuai dengan peruntukannya. Ketidaksadaran dalam membuang sampah secara sembarangan inilah yang dapat merusak pemandangan di area sekitar tempat itu. Saat ini, sangat banyak produk-produk sampah yang pintar di pasaran dalam memecahkan permasalahan sampah bahkan memudahkan pemiliknya. Namun, produknya sangat mahal dan biasanya setiap orang sudah menyediakan tempat sampahnya sendiri dirumah. Oleh karena itu, kami mengusulkan sebuah aplikasi DIY (Do It Yourself) Smart Trash berbasis IoT (Internet of Things) Open Platform. Aplikasi DIY Smart Trash dengan IoT Open Platform ini terdiri dari platform terbuka yang menyediakan monitoring web dan visualisasi interaktif yang ditampilkan dalam dashboard, layanan MQTT (MQ Telemetry Transport), Kafka, database untuk menerima data dan push notification untuk dapat memberitahukan kepada pengguna. Kami juga mnggunakan sistem embedded dan menyediakan source code untuk Arduino, Redbear, Raspberry Pi3 dan Raspberry Pi Zero W untuk membangun DIY Smart Trash. Dengan menggunakan aplikasi DIY Smart Trash, secara tidak langsung dapat mengurangi biaya manajemen sampah di setiap rumah. Selain itu dari segi harga, DIY Smart Trash memiliki harga yang lebih terjangkau daripada yang lain.

Interactive learning is becoming important in teaching and learning. In particular, the electronic board has educational significance in terms of being able to share and discuss learner's contents with instructors. However, the existing electronic board is not easily used in an educational environment due to the high cost and complicated installation process. This paper propose a mathematical model to calibrate the position of user coordinates by installing two laser sensors and a reflector on a wall. We virtually locate 9 points with software. To validate the algorithm, Raspberry Pi2 is used as a virtual sensor and simulation was performed by PC using RS-232 communication. This algorithm is powerful because up to four pre-saved coordinates are used to provide the higher accuracy.

Abstract:

The design of a remotely operated vehicle (ROV) with a size of 18.41 cm × 29.50 cm × 33.50 cm, and a weight of 15.64 kg, is introduced herein. The main goal is to capture underwater video by remote control communication in real time via Ethernet protocol. The ROV moves under the six brushless motors governed through a smart PID controller (Proportional + Integral + Derivative) and by using pulse-wide modulation with short pulses of 1 μs to improve the stability of the position in relation to the translational, ascent or descent, and rotational movements on three axes to capture images of 800 × 640 pixels on a video graphic array standard. The motion control, 3D position, temperature sensing, and video capture are performed at the same time, exploiting the four cores of the Raspberry Pi 3, using the threading library for parallel computing. In such a way, experimental results show that the video capture stage can process up to 42 frames per second on a Raspberry Pi 3. The remote control of the ROV is executed under a graphical user interface developed in Python, which is suitable for different operating systems, such as GNU/Linux, Windows, Android, and OS X. The proposed ROV can reach up to 100 m underwater, thus solving the issue of divers who can only reach 30 m depth. In addition, the proposed ROV can be useful in underwater applications such as surveillance, operations, maintenance, and measurement.

Abstract:

In this paper, a monitoring and controlling process of the mobile base station shelter has been implemented. We have proposed a model that is based on a firebase cloud service and the principle of the internet of things (IoT) to carry out the process of automation. In this model, we have used Raspberry Pi 4 as the main microcontroller of our system that has interacted with a DHT11 Humidity-Temperature sensor and a PIR motion sensor. It's found that the Pi4 module provides efficient analysis, low consumption of power, and effective control of the operation. It turns ON/OFF the electrical appliances automatically inside the shelter. The main advantage of our proposed model is to maintain the temperature and humidity degrees inside the shelter within the required range of operation. Another important advantage is to diminish the tall human exertion level behind the monitoring process throughout the day. The model has been tested through a localhost server via an HTML page. The last one was created with the assistance of HTML and CSS languages to be used as a local user interface. Moreover, the Raspberry Pi 4 was programmed by Python Language to catch up on the reading of the sensors, processes the data, and sends it to the cloud service. Finally, those data will be shown in real-time to the authenticated user on the database of the firebase cloud service.

Abstract:

The underwater environmental monitoring system applying IoT is now developing for 4.0 industry. It helps not only to simplify work but also to increase efﬁciency and reduce costs and execution time as well as ensure health to avoid contact with toxic solutions. In this paper, we first model the process of measuring NH3 concentration manually to automate. Secondly, the proposed model is combined with the process of processing output image automatically and displaying the results on the server. Thirdly, the system is able to measure the concentration by VNC viewer connecting with Raspberry pi4 via WiFi. The result of the NH3 concentration parameter is sent to users quickly to alert promptly when it reaches a dangerous threshold. Experiments show that the system not only ensures fast processing time (less than 5 minutes) but also improves accuracy (up to 80%) comparing with real devices.
