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 ...

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 ...

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 ...

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 ...

There are many annoying issues associated with desktop 3D printers, but perhaps none are trickier than keeping the machine at the proper temperature. Too cold, and printed parts can warp or fail to ...
