Weather station technical data: home-brew open hardware and open source construction, controlled by Atmel ATmega128, using Sensirion SHT85 temperature and humidity sensor, Motorola MPX4115A pressure sensor, PerkinElmer VTP9812FH photodiode, with 433MHz wireless transmission to an embedded linux server.
Notice that the meteostation sensors have not been calibrated and absolute values of e.g. pressure can have a minor offset.
Description of the meteostation construction and firmware source code
can be found here , together with other electronic constructions.
