Distance Based Automatic Fan Controller
An Arduino-based smart fan that automatically turns ON or OFF based on proximity detection using an ultrasonic sensor and controls speed using a DC motor driver.
Description
This project implements an Automatic Fan Control System using an Arduino, an Ultrasonic Sensor, and a DC Motor Driver. The fan automatically turns ON when an object (such as a person) is detected within a specific range and turns OFF when the object moves away. The HC-SR04 Ultrasonic Sensor measures the distance, and the DC motor driver (L298N or L293D) controls the fan’s speed and operation. This system enhances convenience, reduces energy consumption, and is ideal for hands-free operation in homes, offices, and smart environments.
Features: Automatic ON/OFF control.
