Ventilating a room depending on the CO2 rate

By seb, in Internet of Things, january 28,2022.

This week, we are going to talk about a popular topic these days: the ventilation of a work room. CO2 being a good indicator of air "pollution", we are going to see how to automate the opening of motorized Velux skylight windows depending on the CO2 rate inside a room.

Using Yoctopuce sensors with Prometheus and Grafana

By mvuilleu, in Measures, january 21,2022.

A few years ago, we showed you how to integrate Yoctopuce sensors in a Grafana dashboard used with InfluxDB, which was a very common solution at the time. In the mean time, GrafanaLabs has set its sights on another time-series database, Prometheus, which offer many more possibilities to extract data than InfluxDB. We have therefore added to our modules the possibility to provide their data in a format directly recognized by Prometheus.

A canary to detect network intruders

By mvuilleu, in Misc, december 31,2021.

Every now and then, security experts discover new vulnerabilities that affect the security of many computer systems. The month of December 2021 was the occasion of a good example, with the flaw in the log4j library which allows the remote execution of arbitrary code on vulnerable systems. Noting that it seems impossible to definitively guard against this type of problem, we wondered whether the Yoctopuce modules could help detect intrusions before it is too late...
