4. SMART HOME AUTOMATION

- The ESP32 microcontroller is used in this research to build and execute an affordable, stand-alone smart home automation system.This system makes use of local processing and Bluetooth connection, in contrast to traditional systems that depend on human operation or cloud based infr astructure, which may have network latency and connectivity problems. The system combines a number of sensors, including IR, LDR, MQ 2, and DHT11, to continuously monitor ambient factors like temperature, smoke, light intensity, and human presence. To improve safety and ener gy economy, the ESP32 uses this data to control actuators on its own, such as relays, a buzzer, an d a DC moto r.
