Meteostation technical data: home-brew construction, controlled by Atmel ATmega128, using Sensirion SHT75 temperature and humidity sensor, Motorola MPX4115A pressure sensor, LDR07-10 photoresistors, 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.
Description of the meteostation construction and firmware source code can be found here , together with other electronic constructions.
