The M5Stack is a development kit particularly suitable for developing IoT applications (see figure 1). It is Open Source and it is compatible with Arduino. It allows creating IoT applications in a ...

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 ...

The first step is a thermistor, a conceptually simple device: resistance varies with temperature (seriously, how much more simple can a sensor get?). You can measure them by tapping the center of a ...

When life hands you a bunch of crummy capacitors, what do you do? Make a whole bunch of temperature sensors, apparently. The less-than-stellar caps in question came to [pyromaniac303] by way of one of ...

Withings introduced the original ScanWatch in Europe back in 2020, before bringing it to the U.S. the following year, with FDA-cleared features like atrial fibrillation (afib) detection. Announced ...
