Smart Temperature Controlled Fan
In Stock
An Arduino-based smart fan that automatically adjusts its speed according to temperature changes using an LM35 sensor and a DC motor driver.
Description
This project implements a Smart Temperature-Controlled Fan using Arduino, an LM35
temperature sensor, and a DC motor driver. The fan automatically adjusts its speed based on the surrounding temperature detected by the LM35 sensor. When the temperature rises above a set threshold, the DC motor driver (L298N or L293D) increases the fan speed accordingly. This system is ideal for automatic cooling solutions, improving energy efficiency and convenience in homes, offices, and industrial environments.
Features: Automatic speed control
Energy efficient
Real-time Monitoring
Applications: Smart Home and Offices

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
