How to measure wind? (part 1)

By martinm, in DIY, january 11,2013.

Yocto-Meteo owners regularly ask us if Yoctopuce intends to put on the market a sensor to measure wind speed. The problem is that an anemometer contains more mechanics than electronics. We looked at some models available on the market. We concluded that the cheap anemometers were too difficult to hack and that the models designed to be interfaced were way too expensive. We are therefore going to tell you how to create your own anemometer using a Yocto-Knob.

Connect your sensors to the cloud

By mvuilleu, in Measures, december 18,2012.

The #1 application for most USB sensors is certainly to record the measures and draw them in a graph. We have already provided examples in previous blog posts on how to draw measure graphs in several programming languages, but so far you always had make a program of some kind to do this. Today, we show you how to leverage a public cloud-style service named Cosm ( to graph your sensors without writing a single line of code. You will just need to download the latest and greatest version of our VirtualHub, and configure it to upload data to Follow the guide...
