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 ...

Measuring temperature turns out to be a fundamental function for a huge number of devices. You furnace’s programmable thermostat and digital clocks are obvious examples. If you just needed to know if ...

How does a silicon temperature (temp) sensor IC actually measure temperature? These ICs take advantage of the basic temperature-dependent behavior of silicon PN junctions. If you have two PN junctions ...
