In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

This project demonstrates an embedded system that uses a temperature sensor to automatically control the operation of a DC motor (acting as a fan) based on the ambient temperature. This simple and ...

A temperature-controlled fan automatically adjusts its speed based on the surrounding temperature. This project uses an LM35 temperature sensor and PWM (Pulse Width Modulation) control to regulate the ...

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 ...
