Testing some USB-C chargers

By martinm, in Reviews, july 24,2026.

Now that we've converted all Yoctopuce modules to USB connectivity, we thought we'd test some USB-C chargers to see if there's anything interesting to observe. These chargers are normally sold to let you charge your various USB-C devices, but you can easily use them to power Yoctopuce experiments, especially those controlled by YoctoHubs.

Interfacing Sensirion SEN6x sensors

By mvuilleu, in Measures and Reviews, march 27,2026.

Sensirion offers a family of sensors designed to measure parameters relevant to assessing indoor air quality in a building. While largely similar, the various SEN6x sensors differ primarily in the air quality standard they are designed to meet and the types of measures they provide. Let's see how to interface them.

Measuring noise and sound loudness

By mvuilleu, in Measures and Reviews, october 24,2025.

A sound pressure sensor, or noise sensor, is one of those sensors that we've been asked for several times, but don't yet offer. The small on-board processors we use in our modules don't have the computing power to make this measurement, and until now we haven't found an external component we could integrate that met our quality criteria. But there is hope that this will change...

Can I use a dimmer switch with an LED bulb?

By mvuilleu, in Reviews, Electronics and Measures, august 15,2025.

With the disappearance of incandescent and halogen bulbs due to their poor energy efficiency, we're being encouraged to replace the bulbs in our lamps with equivalent LED bulbs. But if you're used to dimming your lights with a dimmer switch, you've probably noticed that your existing dimmer often doesn't work well with these new bulbs. Why is this, and how can we fix it?

The quest for the perfect USB battery, part 4

By martinm, in Reviews, november 15,2024.

The last time we broached the subject, we found a USB battery from WaveShare that could power experiments based on Yoctopuce modules with quite respectable performance: 19 days of continuous use. But we're not giving up just yet. This week, we're turning our attention to products from Voltaic Systems: if the specifications published on their website are anything to go by, there's a good chance that their USB batteries work exactly the way we want them to.
