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-CO2-V2USB sensor with built-in datalogger to measure carbon dioxide (CO2) in ambient air as well as temperature, humidity and atmospheric pressure.

Yoctopuce modules: presentation for people on the go

The post of this week is dedicated to customers who found on the Internet a web site explaining how to build a system based on Yoctopuce modules and who want to build their own system by following the instructions provided on the said web site, but who have no desire to take time to understand how Yoctopuce modules work. If you recognize yourself in this description, you can find here some basic notions from which you cannot escape :-)

Computations in Yoctopuce serial interface modules

A few months ago, we showed you how to use a Yoctopuce serial interface module to automatically handle a serial sensor of type TTL, SPI, RS232, or RS485. This week, we enrich this feature to enable you to perform arithmetic computations directly in the Yoctopuce module, in order to obtain values that you can use straight away with an HTTP callback for example.
