IOT Based Smart Room Automation System using ESP32
The purpose of this project is it demonstrates a complete smart room automation system using ESP32, where multiple appliances and sensors work together to provide automation, safety, and monitoring. It is a practical implementation of IoT-based home automation.
Components Used
ESP32, 2-Ch Relay, DC Fan, AC Bulb with Holder, DHT22, MQ-2 Gas Sensor, IR Sensor, LDR Module, Buzzer, Breadboard, 9V Adapter.
System Working
✅️ AC Bulb is controlled automatically using the LDR sensor (ON in darkness, OFF in daylight).
✅️ DC Fan operation depends on temperature values from the DHT22 sensor.
✅ ️MQ-2 sensor detects gas or smoke leakage and triggers a buzzer alert.
✅ ️IR sensor used for some Motion detection
✅ ️The ESP32 acts as the main controller and can be extended to Wi-Fi / mobile app control.
