The aim of this system is to collect weather data, save or send these data to a base located at 5 km (3.1 miles). The recorder / transmiter is portable and well protected against
open field constraints
(dust and
low pressure jets of water from all directions).

How does it work ?
The operator connects the suitcase to the weather station. He opens the suitcase, switches on the Pocket PC and selects, via its touch screen, to transmit data.
The weather station sent weather data to the pocket PC, on RS port and acquisition card. The Pocket PC computes data and sends these to the base via, depending of the hardware configuration, WIFI (RJ45 connected to WIFI access point) or UHF (RS port connected to UHF transmitter).
In the base, a computer receives computes and displays data on the screen.
