Distance Based Automatic Fan Controller
₹1,450.00
In StockAn 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.

To measure distance using an ultrasonic sensor and display the result on an LCD with an 8051 microcontroller, you’ll need to interface several components: an ultrasonic sensor (e.g., HC-SR04), an LCD (e.g., 16×2), and the 8051 microcontroller.

An XOR (Exclusive OR) gate is a digital logic gate that outputs true (1) only when the number of true inputs is odd. For two inputs, the output is high when the inputs are different. XOR gates can be constructed using basic logic gates or directly with transistors (BJT or MOSFET). Using transistors, we can design compact, efficient circuits for custom digital logic applications.

This project involves controlling a DC motor’s direction using an 8051 microcontroller, with a buzzer and LED indicating the motor’s rotation state. When the DC motor rotates forward, the microcontroller keeps the buzzer and LED off. However, when the motor is rotated in reverse, the microcontroller triggers both the buzzer and LED to turn on as a visual and audible indication of the motor’s reverse rotation
