New! Yocto-Spectral & Yocto-Spectral-C

By Tiago, in New stuff and Measures, june 13,2025.

Some years ago, we were tempted to develop a color sensor based on a simple RGB sensor chip, but the results didn't convince us. Today, we present the Yocto-Spectral and its USB Type-C version, the Yocto-Spectral-C, modules which can measure the light spectrum over 13 channels. Thanks to these measures, they can estimate RGB, HSL, XYZ, and OkLab values, and thus estimate the color seen by the sensor.

Monitoring a solar thermal system

By mvuilleu, in Measures, DIY and Internet of Things, june 06,2025.

If you've ever discussed photovoltaic solar panels with a proud owner, they will certainly have proudly shown you on their cell phone how much electricity they produce every day. With thermal solar panels, on the other hand, remote control is less widespread, as control systems are generally more primitive. So let's take a look at how you can add a simple monitoring system to your domestic water heating system, which could maybe save you a few hundred kWh a year...

Switching the Home Assistant extension to Async

By seb, in Internet of Things and Programming, may 31,2025.

A few weeks ago, we announced our new Typed Python programming library, which offers an asynchronous API in addition to the "traditional" one. This week, we'll take a look at how to use these asynchronous functions by updating the Home Assistant integration we described in this post.

Even more USB-C modules!

By martinm, in New stuff, may 23,2025.

The saga of the new USB-C modules continues. This week, Yoctopuce brings you four modules freshly converted to USB-C connectivity: the Yocto-Temperature-C, the Yocto-Bridge-C, the Yocto-RS232-C, and the Yocto-Buzzer-C. Let's take a closer look...

New product: The Yocto-4-20mA-Tx-V2-C

By mvuilleu, in New stuff, may 16,2025.

Ten years ago, we announced the Yocto-4-20mA-Tx, which enables signals to be transmitted over a current loop using the 4-20mA industry standard. Designed to be inexpensive, it sometimes showed its limits. Taking advantage of the fact that we had to make a version with a USB Type-C connector, we chose to make some major improvements based on experience with the original product.
