You will find below the current temperature, humidity and pressure in Cartigny, where Yoctopuce has its offices. This data is collected in real time by a small PHP script, that polls a Yocto-Meteo USB weather sensor and stores it in a MySQL database for later display. The graph is generated using JpGraph library. A reader suggested to add the dew point on the graph: the closer the temperature comes to the dew point, the more likely fog becomes.
This project is a small application of the Yocto-Meteo module. It is described in more details in a blog article.
