Guiding a spotlight with rangefinders

By mvuilleu, in DIY, march 22,2024.

A month ago, we presented in this blog two products whose tests had proved quite successful: a small rangefinder that worked over 10m, and a small DMX512-controlled motorized spotlight. We thought we'd make a fun little project by combining them, and there's nothing like this kind of testing to see if a product lives up to its promise...

Measuring high concentrations of CO2

By martinm, in Measures and Programming, march 15,2024.

The Yocto-CO2-V2 can measure concentrations up to 40000ppm or 4%, but we're sometimes asked if there isn't a model capable of measuring higher concentrations. The answer is no, but on the other hand, it's easy enough to use Yoctopuce modules to interface other CO2 sensors, such as the K33 ICB-F from Senseair, which can measure CO2 concentrations of up to 10%.

Compiling the C++ v2.0 library

By seb, in Programming, march 10,2024.

A few weeks ago, we released a new version of our C++ library. The main new feature is SSL/TLS encryption for communications. This new feature changes the way to compile our C++ library with your project. Let's take a look at what's new.

Communicating with DMX512 devices

By mvuilleu, in DIY, march 01,2024.

DMX512 is a lighting control standard widely used in theater and nightclub technology. It enables all kinds of stage equipment to be remotely controlled from a central console, simply via a long three-wire bus on which the spotlights are chained. But can a Yoctopuce module be used to access a DMX512 bus?

Testing the TR-EVO-60M-I2C rangefinder

By martinm, in Reviews, february 23,2024.

More or less by chance, we came across the TR-EVO-60M-I2C rangefinder manufactured by TeraBee. It promises a detection distance of 0.5 to 60 meters with a viewing angle of 2°. All this in the volume of a 3cm cube with an I2C and serial interface. At around 100 CHF apiece, we couldn't resist buying one to play with.
