Yoctopuce, USB Sensors and Actuators

USB Sensors and Actuators

Yoctopuce designs, manufactures and sells USB devices to let your computer sit in the real world. Our USB modules are tiny, easy to install and easy to drive programmatically. Among them you will find:


Yocto-SPIUSB to SPI adapter (3.3V or 5V), with built-in data analyzer. Works without driver and without COM port.

Pool control with Home Assistant

As Yoctopuce modules can now be controlled by MQTT, we propose this week a concrete example of their use in a system entirely controlled by Home Assistant. The goal of this project is to obtain a control panel gathering all the important parameters to check the state of a private pool, and to implement some simple regulation automations that can then be easily refined to optimize the pool energy consumption.

The price of double-width enclosures is increasing :-(

If you are using double-width Yoctopuce modules, you are also familiar with the double-width enclosures. At 18 CHF (excl. tax) each, you probably find them overpriced. So do we. But we had to increase their price significantly. And we think the least we can do is to explain why.
