Reed switches, magnets, and Yocto-PWM-Rx

A customer recently contacted Yoctopuce support to ask why his DIY tachometer didn't work with a Yocto-PWM-Rx. We looked into it and, to our surprise, we discovered that generating a clean PWM signal with a magnet and a reed switch was not as easy as one could think.

Using a Yocto-Watt as energy meter

The Yocto-Watt is a small module which is very convenient to measure by USB the voltage, the current, and the instantaneous real power of an electric circuit. As it is also able to integrate the power to compute the total energy for a given lapse of time, some users also employ it to measure the energy that a system consumes, and we have recently improved this feature.
