[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

I missed a rather nice precision humidity and temperature sensor from Sensiron when it first emerged. SHT45 is only 1.5 x 1.5 x 0.5 and is specified at ±1.0% relative humidity and ±0.1°C temperature ...

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 ...

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 ...

A low-power, compact, RH and temperature sensor eases the challenges associated with accurately, reliably, and consistently measuring these important environmental parameters. Features of the new TI ...
