Rancangan Bangun alat ukur daya listrik sistem kontrol dan deteksi on/off berbasis IoT

Abstract

This study aims to design and implement a circuit that functions to determine the amount of electricity consumption, current, voltage as well as controlling the distance of the remote lamp and detecting the on/off lights. This tool requires a PZEM-004T sensor, sensor, LDR sensor, and relay. The PZEM-004T sensor functions to determine the amount of current and voltage, the LDR sensor functions to determine whether or not there is light on the lamp, and the relay functions to disconnect or connect the current. This circuit uses the ESP32 microcontroller which is programmed via the Arduino IDE and displayed on the BLYNK application. The way this tool works is that if people want to know the consumption of electric power, current, voltage or control the lights remotely and also detect the on/off lights more quickly and concisely, then the user only needs to connect the device to a smartphone using the internet. Then the tool will calculate and work according to orders. After that it will be controlled or displayed on the BLYNK application.
