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-PT100Small device to measure the temperature with very high precision, using a PT100 temperature sensor (2, 3 or 4-wires supported). The device includes a built-in data logger to record measurements. The PT100 connection is electrically isolated from the USB bus.

YoctoHub-GSM-3G-EUHub enabling the connection of 3 Yoctopuce modules directly on a 3G GSM cellular network (900MHz/1800Mhz used in Europa, MIddle-East, Africa, Asia and Pacific), with a built-in timer.

Optimizing communications with Yoctopuce devices

Experienced users of Yoctopuce modules will sooner or later wonder how much data needs to be transferred to retrieve the measures from Yoctopuce sensors. It can be the case to optimize GSM consumption, as it we discussed in a previous post, but also simply to improve the performances of an application where the modules are connected by USB but where the measures must be read very quickly. So here is a detailed explanation to know everything and optimize everything...

Using Yocto-Visualization with a YoctoHub-GSM

Yocto-Visualization enables you to very easily visualize data from Yoctopuce sensors, whether they are connected by USB or through a network hub, with the exception of the YoctoHub-GSM. Indeed, the GSM SIM cards available to ordinary people do not have a public IP address and are behind a NAT filter, which prevents the Yocto-Visualization to connect itself directly on it. However, there is a way to work around this issue.
