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 ...

As connected as we are, reliable and affordable internet is still a luxury in the far reaches. [kohleick’s] country home is not just remote; with temperatures dropping to -30C in the winter, it’s ...

I'm working with a uC controlled fan/temp contoller. In that regard I'm very interested in how to control temperatures the best way. The board will be able to measure 8 temp probes and control 8 fans ...

I was wondering about a temperature controlled case fan (80mm or 120mm) that has its own temperature sensor (not controlled by the motherboard) to control its RPM. Are all of them like this or are ...

Whether you’re using a soldering iron or a table saw, ventilation in the shop is important. Which is why [Atomic Dairy] built a monster air cleaner called the Fanboy that looks like it should be ...

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 ...
