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.

A screen that consumes (almost) nothing

The issue with most screens is that they need to be constantly powered to display information. There is however an exception: the e-paper (or electronic paper) technology. This week, we take advantage of this technology to build a connected screen able to work for months on a single battery charge.

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...

Creating a connected night light

IKEA makes pretty ghost-shaped night lights, but the power cable of these "SPÖKA" is very thin. One children has torn this cable and called Yoctopuce for help. At first, we thought that we would simply fix the power cable but, in the end, we decided to improve this night light by transforming it into a "connected night light" with a Yocto-Color-V2 and a YoctoHub-Wireless-SR.

From the start, sensors and actuators produced by Yoctopuce are USB devices. But you can enhance them with network connectivity very easily thanks to the YoctoHubs. As part of our "Yoctopuce for beginners" series, we are going to have a look at these YoctoHubs and discuss their advantages and disadvantages.
