Abstract

DC motors (Direct Current) have become a key component in various industrial applications and electronic devices. With technological advancements, monitoring and maintenance of DC motors have become increasingly important to ensure efficient operation and prevent unexpected failures. One way to enhance DC motor monitoring is by integrating RPM and temperature sensors, which can provide crucial information regarding the motor's operational conditions. This research aims to develop a tool for detecting the condition of DC motors by comparing temperature and motor speed variables. The components used in assembling this device include an IR Obstacle Sensor, Thermocouple Sensor, ESP32 Microcontroller, I2C LCD, and Servo. The working principle of this research tool involves connecting it to a 220V power source, then switching the ON/OFF switch. Once the device receives power, the sensors and other components will be ready, indicating that they are prepared to read the pre-programmed instructions. For testing the device, first, the DC motor is activated by setting the PWM value between 0-255. Then, the thermocouple sensor and RPM sensor will read the motor's condition when the DC motor is on, which will be displayed on the LCD. If the DC motor temperature exceeds 50°C, the LED will turn ON, indicating that the motor's temperature is above 50°C and providing information on the motor's speed.Keywords: ESP32, K-Type Thermocouple, RPM, DC Motor, IoT

Abstract

The ever-increasing need for clean water requires innovation in water quality management and monitoring. This research aims to design and develop a water turbidity monitoring tool and an automatic water pump based on the Internet of Things (IoT) using the ESP32 microcontroller. The main objectives of this research include implementing ESP32 as the main controller, developing a system that can detect and monitor water turbidity levels in real-time using a turbidity sensor. The research results show that the designed tool is able to work well, with a measurement error rate of less than 5%, which shows high accuracy. The turbidity sensor and ultrasonic sensor work optimally, able to determine whether the water is clear or cloudy, and control the water pump automatically. The water pump will stop if the water level exceeds 32 cm or the water turbidity value exceeds 20 NTU. This system successfully meets the initial research objectives, offering an efficient and reliable solution for water quality management.

Abstract

Innovative technology solutions are developed to help patients manage their medication more effectively. Diabetes is a chronic disease that requires regular monitoring of blood sugar levels and proper regulation of medication consumption. This system is designed to assist diabetics in remembering when to take their medication and to ensure the correct dosage in accordance with the doctor’s recommendations. It utilizes an IoT device connected to a mobile application or web-based platform, allowing users to receive notifications at predetermined times. Additionally, the system includes patient condition monitoring features, such as blood sugar level tracking synchronized with measurement devices. The collected data is transmitted in real-time to the application, enabling both patients and medical personnel to monitor treatment progress and make necessary adjustments. Through the integration of IoT, this system not only enhances patient adherence to medication schedules but also provides better analysis of medication effectiveness and potential risks, thereby minimizing negligence in medication consumption. The implementation of this technology has the potential to significantly improve the quality of life for individuals with diabetes.

Abstract

The chemical and process industries require precise control systems to manage critical parameters, such as the pH level in solutions, especially in the treatment of acidic liquid waste. One of the main challenges in this industry is the effective neutralization of acidic waste to prevent damage to the environment and infrastructure. IoT-based pH sensors offer an innovative solution by enabling real-time, remote monitoring and control of pH levels. With IoT integration, pH sensor data can be accessed directly, improving operational efficiency and decision-making accuracy. Furthermore, automatic pH regulation based on collected data minimizes human error and enhances safety. In testing, the ultrasonic and TDS sensors integrated with relay and motor pump modules demonstrated 100% accuracy in controlling devices based on distance and TDS values. The entire system operated with a very low error percentage, confirming its reliability for application in the chemical industry.Keywords: Internet of Things (IoT), pH sensor, pH control, liquid waste, ultrasonic sensor, TDS sensor, automation, chemical industry

Abstract

The management of water resources in dams relies heavily on reliable control and monitoring systems to prevent disasters such as floods and droughts. This research aims to design and build an automatic control system for dam sluice gates and real-time water level monitoring based on the Internet of Things (IoT). This system uses ultrasonic sensors to measure water levels, microcontrollers as control centers, and servo motors to automatically adjust the sluice gate opening and closing based on a predetermined height threshold. Water level data is sent and displayed in real-time through an IoT platform so that it can be accessed by users via smartphones or computers\cite{alfariski2022automatic}. The test results show that the system is able to monitor the water level with good accuracy and control the floodgates responsively according to actual conditions in the field. Thus, this system is expected to improve the efficiency of dam management and provide early information for disaster mitigation

Abstract

Growth and development of infants are crucial aspects that need to be regularly monitored, with height and weight serving as key indicators of nutritional status. This study aims to design and develop a technology-based system to automatically monitor the height and weight of infants using ultrasonic sensors and load cells. The system is designed to provide accurate, practical, and continuous real-time measurements, integrating technologies such as ESP32, LCD, and Blynk application. Test results demonstrate that the system achieves high accuracy with an error percentage below 1%, along with optimal performance of the ultrasonic sensor (distance up to 80 cm) and load cell (weight up to 10 kg). Among the 6 samples tested, 2 infants were categorized as undernourished, 4 as normal. This system is expected to simplify the monitoring of infant nutritional status, support early detection of health issues, and contribute to improved growth quality

Abstract

Motorcycle theft and robbery have drastically increased the ease of losing motorcycles in public places, especially motorcycles that do not have more safety such as keyless in general. The current motorcycle security system still uses the key as the main security or uses additional security electronic devices such as an alarm that sounds if there is a hard touch on the motorcycle. However, security like this is not fully guaranteed that the motorcycle is safe. The problem of this research is how to design a security system based on RFID, GPS and telegram applications. The purpose of this research is to design a motorcycle security system based on RFID, GPS and telegram applications that can monitor and secure motorcycle vehicles and know the difference in distance between GPS coordinate points to facilitate detection of the location of our motorcycle and also to turn on the motorcycle electricity must scan the identity of the motorcycle owner. The research method consists of hardware and software design and testing of the RFID system, GPS testing, monitoring testing through the telegram application and testing the overall electric current. In the RFID distance test, the tag is perfectly read up to a distance of ± 3 cm with a success rate of 100%. However, at a distance of ±4 cm and above, the readings were inconsistent, and above ±5 cm, the tags were not read at all. GPS sensor testing was conducted to detect the location of the motorcycle based on latitude and longitude coordinates at several points. The difference between two points is calculated using the Euclidean distance formula, where the difference in latitude and longitude is converted into meters. For example, a 1-second latitude difference is equivalent to 30.92 meters, and a 2-second longitude difference is equivalent to 61.85 meters. By calculation, a distance difference of 69.14 meters is obtained between the two points. This shows that the GPS sensor can detect position differences with sufficient accuracy
