Monitoring Long-Distance Light Control Combination of Switch and Cross Based on Iot

Abstract

The development of industrial electronics technology has undergone significant changes with the advent of the Internet of Things (IoT). Remote control of lights has become very easy with the help or collaboration with other devices such as the ESP32, which already has several input and output pins as well as Wi-Fi and Bluetooth availability. Commands via smartphone are executed using a Telegram Bot to instruct the ESP32 to activate or deactivate the relay. The relay contact, which functions similarly to a toggle switch, can turn the light on and off remotely. The combination with a cross switch allows the light in a building to be operated from two locations and can be applied in corridors or staircases. In addition, remote checking of the lamp status can still be performed. From the research conducted, a prototype module for remote lamp control using a toggle switch and a cross switch yielded the expected results.
