Control and Monitoring Automatic Floodgate based on NodeMCU and IOT with Fuzzy Logic Testing

Flood is still a problem that always been a mayor obstacle in several big cities in Indonesia such as DKI Jakarta. If the rainfall so high and river can be accommodate the rainfall, there will be flooding. So that river water doesn’t overflow, it is necessary to make a floodgate in the river flow. One of the previous studies that has been carried out regarding the control and monitoring of water dam gates is researched by Fahruddin. 2014 from the Faculty of Science and Technology, Makassar State Islamic University: Describes the design of a device capable of monitoring the height of water activity in the reservoir and controlling the floodgates automatically according to the height of water activity. The research that the writer is currently carrying out is the design method which consists of a series of sensors, NodeMCU microcontrollers, and Stepper Motors. The workflow of this system is when the water rises or falls, it send a signal to the sensor. And then the signal will be input for the microcontroller which is then processed to turn on the motor, so that it can open or close the floodgates, and send information to the indicator screen and Telegram application. After the experiment is carried out, it can be said that the system can work properly, namely when the ultrasonic sensor experiment, it was found that the sensor has been sent an output signal that was in accordance with the water level in actual condition. Based on testing using the fuzzy method, it was found that opening value at the floodgate obtained during the test had an average accuracy rate of 91% with an error difference of 9%

Automatic Sluice Monitoring Based On The Water Ph In a Brackish Water Pool Using a Web Server

Fisheries are one of the most potential sources of foreign exchange for the country. Water quality in fish farming in freshwater ponds is a very important part because the growth and age of fish is strongly influenced by temperature and changes in dissolved oxygen levels, water pH and salt salinity. Fish farmed in freshwater ponds are thought to be more sensitive to sudden changes in water quality. In order to continue to produce good quality fish, a tool is needed to control the pH of the water in brackish water ponds where fish farming is carried out. A prototype of a brackish water pond with automatic sluice is designed that can maintain pH stability in a pond filled with brackish water. The floodgates are driven using a servo motor with an Esp 32 microcontroller. The system is able to accurately measure the pH of the water and the results of the measurements are sent to the database via Esp 32 and displayed via a web server. When the pH value in a brackish water pool is less than 7, the floodgates containing salt water will open automatically to stabilize the pH in the brackish water pool. However, if the pH value in the brackish water pool is 8, the door containing fresh water will open automatically.Keywords: Water, Esp 32, fish, pond, brackis

Integrated Control of River Overflow Based on Microcontroller

This river overflow control is carried out in stages and in an integrated manner. The river water level is detected in real time with four levels, namely normal, alert, standby, and beware. The overflow of river water at each level will flow automatically through three floodgates that work simultaneously, followed by turning on three water pumps which also work simultaneously. The water flowing from the floodgates is channeled into an irrigation area, while the pumped water is flowed into a reservoir. This river overflow control is carried out in an integrated manner between monitoring the river water level, opening and closing the floodgates, working the pump, and detecting the reservoir maximum level. When all the floodgates are fully open and all pumps are running, and the water level in the reservoir has reached the maximum limit, the alarm will sound. Such conditions are stated in a state of over flow or out of control. This control is based on a microcontroller so that it has a fast response with minimal components. The control system is designed and made in a miniature form that runs well and with a fast response time

User Acceptance for Multitask IoT Monitoring and Controlling System for Salt Ponds

The process of making salt is still done manually by filling water into reservoirs and plots which require salt farmers to visit their farms periodically. This is mainly because the speed of the salt crystalization process is always inconsistent due to salt concentration in seawater and the weather. This study aims to build a new prototype of a water level monitoring system in reservoirs and plots in salt ponds then measure the water's salinity value, which will be reported to the farmers. The method used in this research is prototyping, which includes system requirement analysis, rapid design, prototype building, system evaluation, and system  improvement. The system was tested using the black box method, namely testing all system functionality and determining user satisfaction with questionnaires. The functionality test results, including monitoring the water level and the pump control, show that the prototype functions correctly. The designed system can send information in the form of water level values in reservoirs, water levels in plots, and salinity values with linear sensor accuracy with measurement results with conventional measuring instruments with standard error values of 0.485, 0.44, and 0.72, respectively. Applying this system will ease farmers’ monitoring of water levels and controlling irrigation in reservoirs and plots

Design of automatic watergate system using ESP32 microcontroller based on Fuzzy Logic Method

Automatic watergate systems are designed to allow the watergate to run automatically based on an ideal condition for agricultural land. The sensor will be a crucial role in this automation system. In this system, the input of the system is come from ultrasonic and moisture sensor, while the output is how big watergate will be open. The ultrasonic sensor is widely used in the design of watergate system because they provide effectively measuring a water level. And also, soil moisture sensor was used to measure the percentage of humidity of the land. In order to process this input, we used a fuzzy logic to determined the output, which is the percentage of watergate will be open. By using Fuzzy logic, the machine can do an output based on conditions in the input that has been programmed. In this research, a Fuzzy Logic Control method system will be implemented to control the watergate so it’s can be opened level to level. Authors exert three levels of watergate open, that are 0%, 50%, and 100%. The input in this study is the water level and the humidity of land. Simulations have been carried out to get the value of the membership function. The simulation is carried out using a case study, where the input from the ultrasonic sensor is 6 cm and 88% on soil moist sensor

Fuzzy Logic Based Dam Water Shutter Control System by Using Water Level and Rainfall Condition in Raining Season

A robust water shutter management system ensures that the water does not overflow and destroy or damage the dam. During the rainy season, care must be taken when dams conserve water, if the reservoir volume is too high, the risk of dam failure may be increased. So water level control is a special matter in the rainy season. Fuzzy logic sets provide better control than binary logic-based methods because they are used to determine the meaning of qualitative values for controller inputs and outputs, such as small, medium, and large control actions. This system used the fuzzy logic control theory in the water shutter management system to get smoothness motor control values of small, very small, medium, large, and very large. The system uses ultrasonic sensors to detect water levels, rain sensors to detect rain, and fuzzy logic controls to control the PWM duty cycle to the shutter gate motor driver circuit based on the detection of these two sensors. This control strategy is implemented with Arduino Uno

Dam is a building used by humans as a regulator of water discharge in a river. In the tropics the big role of dams occurs throughout the year. The active role of dams in life is to store water reserves in the summer, as well as reduce the risk of flooding that occurs during the rainy season. This research discusses the process of monitoring a dam using the Outseal Mega V2 PLC as a control device for the entire system supported by an analog module as an analog value reading device (ADC). The ADC value will be obtained through the output voltage from the potentiometer which is used instead of the water level sensor. The ADC value will then be processed by the PLC to make a decision. This research is supported by an HMI interface using Haiwell Cloud Scada Develop software so that machine-human communication can be carried out and real-time monitoring is achieved

Benchmarking Applicability of Cryptographic Wireless Communication over Arduino Platforms

The spaces around us are becoming equipped with devices and appliances that collect data from their surroundings and react accordingly to provide smarter networks where they are interconnected and able to communicate with one another. These smart networks of devices and appliances along with the applications that utilize them build smart spaces known as Internet of Things (IoT). With the on growing popularity of such smart devices (e.g., smart cars, watches, home-security systems) and IoT, the need for securing these environments increases. The smart devices around us can collect private and personal information, and the challenge lies in maintaining the confidentiality of the collected data and preventing unsecured actions—from tapping into surveillance cameras to tracking someone’s daily schedule. For example, digital health, devices that record personal data from blood pressure, heart rate, weight and daily activities sensors are storing the personal data of users for processing and monitoring and may give future recommendations. If such personal information reaches unwanted third parties who distribute or use the data without user consent or knowledge, they are attacking the user’s confidentiality. Therefore, selecting the appropriate security protocols and procedures is critical. The limited processing, storage and power capabilities. In this thesis, the focus is to provide an experimental benchmark study that shows the cost (e.g., processing time of encryption and decryption algorithms) of applying different security protocols on restricted devices equipped with lightweight Bluetooth or Wi-Fi communication modules over the Arduino Uno sensor platform

Node assembly for waste level measurement: embrace the smart city

Municipal Solid Waste Management Systems (MSWMS) worldwide are currently facing pressure due to the rapid growth of the population in cities. One of the biggest challenges in this system is the inefficient expenditure of time and fuel in waste collection. In this regard, cities/- municipalities in charge of MSWMS could take advantage of information and communication technologies to improve the overall quality of their infrastructure. One particular strategy that has been explored and is showing interesting results is using a Wireless Sensors Network (WSN) to monitor waste levels in real-time and help decision-making regarding the need for collection. The WSN is equipped with sensing devices that should be carefully chosen considering the real scenario in which they will work. Therefore, in this work, three sets of sensors were studied to evaluate which is the best to be used in the future WSN assembled in Bragança, Portugal. Sets tested were HC-SR04 (S1), HC-SR04 + DHT11 (S2), and US-100 (S3). Tests considered for this work were air temperature and several distances. In the first, the performance of each set to measure a fixed target (metal and plastic box) was evaluated under different temperatures (1.7 - 37 ℃). From these results, two best sets were further used to assess distance measurement at a fixed temperature. This test revealed low absolute errors measuring the distances of interest in this work, ranging from 0.18% to 1.27%.This work has been supported by FCT - Fundação para a Ciência e Tecnologia within the R&D Units Project Scope: UIDB/05757/2020, UIDB/00690/2020, LA/P/0045/2020, UIDB/50020/2020, and UIDP/50020/2020.
