I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

This project demonstrates the development of an energy-efficient system to regulate a fan's speed automatically based on room temperature. By integrating an Arduino Uno microcontroller, a DHT11 ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

This project demonstrates a temperature-based fan control system using an Arduino Uno. The system reads ambient temperature via a DHT11 sensor and adjusts the speed of a 12V exhaust fan accordingly ...
