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...

Detecting whether an appliance is currently working

A customer asked us how to detect whether a washing machine is working or not. The first idea that comes to mind is to measure its consumption with a Yocto-Watt, but there are ways of doing things more subtly for less money.

A fun and musical DIY project

Python is well-suited to tinkering with prototypes based on Yoctopuce modules: the code is compact, so it can be written fairly quickly, and open source libraries are readily available to interface external elements not directly supported by Yoctopuce modules. Today, we're going to show you just such an example...

A connected dry box

This week, we're going to do a simple DIY project that will be of interest to anyone involved in 3D printing. We're going to make a box for storing filaments while monitoring humidity.

Timing, RFID, and radio-controlled cars

In addition to reading and writing tags, the Yocto-RFID-15693 module API allows you to program a callback that is called every time a tag enters or leaves the antenna field. And these callbacks are time-stamped. It's only a short step from there to using this feature to build a stop-watch application, a step we didn't hesitate to take.
