Weather station technical data: home-brew open hardware and open source construction, controlled by Atmel ATmega32 (new version has ATmega128), using Sensirion SHT75 temperature and humidity sensor, Motorola MPX4115A pressure sensor, PerkinElmer VTP9812FH photodiode, La Crosse TX20 anemometer (not heated - under certain conditions azimuth or speed can freeze), and rain gauge based on the TFA 47.3003 with self-made heating, 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.
Magnitude of the pressure offset can be estimated by comparing the QNH with respect to METAR PRAHA
Description of the meteostation construction and firmware source code
can be found here , together with other electronic constructions.
