Weather station

weather-stationAVR (Atmel) based weather station. Was developed for remote sensing of micro-climate parameters.

Controlled by ATmega8A Atmel datasheet *.pdf CPU. CPU reads sensors and send data to PC via serial interface (RS-232 , 9600 bod). PCB board was developed in size which allow further installation into the Gainta G-203CMF Gainta datasheet *.pdf housing.  Current weather station could measure the next parameters:

  • Pressure (BMP085) 225…826 mm.Hg.
  • Temperature (DS18B20, DHT22, BMP085) -50…+50°С
  • Humidity (DHT22/AM2302) 0…99%
