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:


YoctoHub-Wireless-gHub enabling the connection of 3 Yoctopuce modules directly on a wireless network (802.11g), with a built-in timer.

Yocto-milliVolt-RxSmall USB module to measure small and very weak electric signals. The device can convert the voltage measure to an equivalent physical measure on the fly, and includes a built-in datalogger.

And what's smoking ?

Sending and receiving SMS from a software

We have just added a new feature to the YoctoHub-GSM. If you update your firmware, you will be able to use it to send and receive SMS. This is might not look very useful to access a Yoctopuce sensor, but it opens the door to new use-cases for the YoctoHub-GSM itself. For instance, you can now implement two factor authentication.

A pseudo terminal for the Yocto-Serial

Many home automation projects use mini-PCs running under Linux. Some of these mini-PCs have an HDMI output, but other, such as the OLinuXino, don't have a video output. In this case, the solution to configure these boards is to use a serial console. The problem is that no computer has a serial port anymore and if you have an old enough computer to have an RS232 port, you can't use it because the RS232 port works in 12 Volts. The traditional solution is to use a USB-serial adapter sold by the constructor. But you can also use a Yocto-Serial.
