Home Automation using esp-32 with App

This project demonstrates IoT-based control of electrical loads such as AC appliances, motor, fan, and light using a Wi-Fi enabled microcontroller. Loads can be turned ON/OFF remotely through a mobile app or web dashboard over the internet.

Main Components Used

• ESP32 / ESP8266 Wi-Fi Module
  Acts as the brain of the system. It connects to Wi-Fi and receives control commands.

• 4-Channel Relay Module
  Works as an electrical switch to control high-voltage AC devices safely using low-voltage signals.

• DC-DC Buck Converter
  Steps down voltage to power the ESP module and relay safely.

• Loads (Demonstration Units)

  • AC Load

  • Motor

  • Fan

  • Light

How It Works (Simple Flow)

1. User sends ON/OFF command via mobile app / web interface

2. Command reaches the ESP32 via Wi-Fi

3. ESP32 activates the corresponding relay channel

4. Relay switches the connected electrical load

5. Device turns ON or OFF instantly
