Yoctopuce, USB sensors and actuators

Meet Yoctopuce

Yoctopuce designs, manufactures and sells USB devices to let your computer sit in the real world, not in the cloud. Our USB modules are tiny, easy to install and easy to drive programmatically. Among them you will find:


Yocto-PWM-RxThat isolated device can decode PWM signals. It can be used as a pulse counter as well.
