How to sort objects by color?

By Tiago, in Measures and DIY, october 03,2025.

A few months ago, Yoctopuce launched a color sensor based on the spectral analysis of light. This module not only provides raw measures, but it also estimates the color of the object that produced the measured spectrum. As there is no mathematical formula directly applicable to this task, this feature has required a fair amount of experimentation to verify the reliability of the obtained results. Today, we present one of the test methods we used.

Correcting the linearity of a PMP24 proportional relay

By mvuilleu, in Electronics and Measures, september 26,2025.

Specialized online stores offer a variety of proportional control solid-state relays, enabling you to control, for example, the output power of a resistive heating element more precisely than with a simple on/off relay. However, these components are often not as proportional as their name suggests, which can affect how the control process works. So we're going to take a few measures to see if this can be improved.

New: The Yocto-MaxiThermistor-C and the Yocto-Color-V2-C

By martinm, in New stuff, september 12,2025.

This week, Yoctopuce once again presents two new additions to the USB type-C module family. They are the Yocto-MaxiThermistor-C and the Yocto-Color-V2-C. Let's take a closer look, shall we?

Recording animations with the Yocto-Watt-V2-C

By mvuilleu, in Measures and Electronics, september 05,2025.

To illustrate last month's post on the operation of dimmers, we used small animations made manually on the basis of images produced by the Yocto-Watt-V2-C. In doing so, we thought it would have been handy if the Yocto-Watt-V2-C had been able to record measure sequences itself in animated form. So this week, we did just that :-)
