Traditional fans run continuously or require manual control, often leading to energy waste. This project creates a smart solution: a temperature-sensing fan controller that turns ON/OFF or adjusts ...

ThermaPID is a temperature control system implemented on Arduino using a DHT11 sensor, a brushless pc fan (5V 0.4A), and a PID controller. The fan speed is automatically adjusted via PWM to maintain a ...

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 ...
