Calibrating a Yoctopuce sensor

By seb, in Measures and Programming, october 16,2016.

Generally, we always try to use sensors which do not require any calibration. But, in some cases, we cannot work around this step, in particular if you need to compensate an external perturbation. All the Yoctopuce sensors have the possibility to automatically apply a correction to the value returned by the sensor. Let's see how it works.

Accelerometers and gyroscopes: fantasy vs. reality

By mvuilleu, in Measures, september 30,2016.

The widespread use of game controllers and augmented reality tools based on accelerometers and gyroscopes raises many ideas for applications. However, some of these applications are more a fantasy than a reality, as enthusiasm sometimes makes us forget some basic physical principles. So, here is a little reminder to help you avoid cruel deceptions...

Monitoring electric consumption over GSM

By mvuilleu, in Measures and Internet of Things, september 09,2016.

A few years ago, we explained why the Yocto-Watt is limited to 16A and we gave you some clues on how to measure high currents. But, at that time, we didn't have a simple solution to offer for the most current application: measuring and transmitting the main consumption parameters of a power distribution panel. This gap is today filled and we offer you a detailed solution, easy to implement, based on commercial components.

While exchanging with our customers on the best ways to interface industrial controllers, we noticed that nowadays the small secrets enabling you to use an RS485 interface were sometimes unknown from engineers implementing computer or internet based automation. So here is a quick remedial course...

Passive monitoring of an empty house

By martinm, in Measures and Internet of Things, april 29,2016.

Let's imagine an isolated house, unoccupied most of the time, with the heater set to the minimum to prevent pipes from freezing. No Internet, no phone... only electricity. How to make sure, without going there, that: a/ the boiler has not broken down , b/ no one settled in inside the said house without your knowledge? We had a few ideas...
