IoT-Based Smart Switch Board Using ESP32
I developed a compact IoT home automation device using the ESP32 microcontroller and a relay module that can be installed inside a standard electrical switchboard. The system allows users to control household appliances such as lights and fans remotely through the internet.
The ESP32 serves as the main controller, utilizing its built-in Wi-Fi capability to connect to a home network. It communicates with a cloud platform or mobile application, enabling users to turn appliances ON or OFF from anywhere. The relay module acts as an electrically operated switch, allowing the low-voltage ESP32 to safely control high-voltage AC appliances.
The device is designed to:
Fit inside existing switchboards without major modifications
Operate appliances remotely via smartphone or web interface
Provide real-time control over lights and fans
Enhance convenience, energy efficiency, and smart home integration
This project demonstrates the practical implementation of IoT in home automation, combining embedded systems, wireless communication, and electrical control into a compact and efficient solution.
