Interfacing MLX90393 sensors with a Yocto-I2C

By martinm, in Programming, may 31,2024.

A customer recently asked us for help interfacing a Melexis MLX90393 magnetic field sensor with a Yocto-I2C. We figured that, if we had to do the integration work, we might as well let everyone benefit from it.

RFID and key management

By martinm, in Programming and DIY, may 23,2024.

In the past, we've been asked several times whether it was possible to build a key management system based on Yoctopuce modules. Of course, we're talking about keys for opening locks, not cryptographic keys. We did propose a modest project a few years ago, but with the arrival of Yocto-RFID-15693, we can think bigger.

Synchronization of autonomous communication scripts

By mvuilleu, in New stuff and Programming, april 19,2024.

One of the special features of Yoctopuce serial communication modules, such as the Yocto-I2C, the Yocto-RS232, and the Yocto-RS485-V2, is that they can autonomously execute small communication jobs, for example to query sensors. We have recently added the ability to synchronize these automatic exchanges to precise time constraints.

Why do browsers block VirtualHub v2?

By seb, in Programming and Misc, march 29,2024.

We've received a few messages from customers who were surprised the first time they used VirtualHub v2 (still in beta). Indeed, the first time you connect to the VirtualHub v2 web interface, the browser blocks the page and displays a big warning about an invalid certificate. But don't panic! It's nothing serious. We'll explain everything.

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%.
