A Raspberry Pi-based Oregon Scientific weather station that also supports the Bosch BMP085/180 temperature and pressure sensor.

• Python >=2.7 and <3.0
• cherrypy >= 3.0
• jinja2
• sqlite3
• RPi.GPIO
• wiringPi
• a 433 MHz radio with AM demodulation, e.g., QAM-RX3-433

1. Wire up the radio, LEDs, and pressure sensor

2. Build the decoder.so extension via 'make'

3. Create the initial database in the 'archive' directory using the 'initDB.sh' script

4. Install the logrotate configuration file in /etc/logrotate.d

5. Run the script via ./wxPi.py

Oregon Scientific

• 5D60 - BHTR968 - Indoor temperature/humidity/pressure
• 2D10 - RGR968 - Rain gauge
• 3D00 - WGR968 - Anemometer
• 1D20 - THGR268 - Outdoor temperature/humidity
• 1D30 - THGR968 - Outdoor temperature/humidity

Bosch

• BMP085
• BMP180

The data formats used for these sensors come from:

• https://github.com/tomhartley/AirPi
• http://learn.adafruit.com/using-the-bmp085-with-raspberry-pi/overview
• Trial and error

Presumably other sensors that transmit v2.1 or v3.0 sensors are also supported if you know the data format.
