Thanks to the FroggyProfessional software, XPro3 allows Pressure, Temperature, Humidity measurement.

Self powered by RS232 link, it is able to provide these 3 value every minute.

In fact every 6,5 secondes it measures pressure, humidity, and temperature, that 8 times one after the other and finally calculates the average and (ouf ! ! !) waits for the request of your PC to transmit the result, after what it restarts for 8 measurements of the 3 data.
