Abstract

In this study, a tool is designed to monitor the temperature on the busbar of the Low Voltage Sub Distribution Panel (LVSDP) based on the Internet of Things. This tool uses the internet network to receive data from a sensor in real-time. The tool in this study is designed to detect the heat generated by the busbars of each phase installed in the LVSDP. Real-time display on the smartphone provides notification if the temperature on the busbar has exceeded the preset set point. To monitor the temperature on the busbar, real-time monitoring is needed which will make it more convenient for technicians to carry out maintenance. Monitoring the temperature on this busbar will be carried out by utilizing technology from IoT which will be connected to the internet and integrated with smartphone devices. In this study, the authors will use the ESP32 module as a medium for receiving, storing, and displaying data on smartphone devices. ESP32 is a module often used for IoT projects. Equipped with Wi-Fi and Bluetooth features and has a Dual-Core Microprocessor which will make data processing faster. To be able to receive temperature data, an infrared MLX90614 sensor is needed. The MLX90614 infrared sensor is an electronic component that functions to detect heat without touching the object whose heat is to be measured because this sensor is facilitated with infrared light which can be directed at the object.

Abstract

Electricity is a basic need of human beings. The consumption of electricity usage is getting bigger and bigger. Electricity usage is usually wasteful due to lack of public awareness and ineffective use of electricity. With this problem, the author aims to design loT-based electric power usage monitoring system in home electrical appliances. This tool is designed using sensors to detect the value of the voltage and current of the load attached to the electricity but still using the BLYNK application as a server and application to monitor the use of electric power through a smartphone application. The measurement results include the data of current, voltage, and electrical power used. This system can also remotely switch appliances ON/OFF. The test was conducted by comparing the results of the power value from the power meter with the power value in BLYNK application. After the test, the results of the comparison between the monitoring tool and the power meter measuring instrument obtained an average power error value of 0.5%. So that the accuracy value of the tool can also be 99.5%. With a large accuracy value, it means that the tool works well and can be used to monitor the use of electrical energy in households.
