This is an interesting project circuit which automatically switches the fan when it detects the temperature inside the device greater than its threshold value. We know that electronic devices produce ...

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 ...

How to build a proportional controller that starts a cooling fan when circuit temperature passes a threshold, speeds up the fan as the temperature rises, and slows down and stops the fan when the ...

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 ...

We show you how to wire in an electric fan relay kit with a thermostatic switch. If you've got an electric cooling fan on your classic car or hot rod and you want to know how to wire it with a relay, ...
