DIGITAL THERMOSTAT

This project is designed to monitor the surrounding temperature and automatically control a relay based on a user-defined temperature setting. The temperature sensor continuously reads the current temperature and sends the data to the microcontroller for processing. The system then compares the measured temperature with the user-set value and switches the relay ON or OFF accordingly. This allows a connected device, such as a fan, motor, heater, or cooling system, to operate a
