The Experiment: Arduino Intercepting Oregon Scientific 433Mhz Wireless Weather Station Data. Build a 433Mhz wireless weather station receiver around an Arduino UNOmicro-controller, to receive weather sensor data from an Oregon Scientific Wireless Weather Station.

Recently acquired a free broken Oregon Scientific Wireless Weather Station  anemometer, wind vane, rain gauge and inside thermo-hygro for part. The only broken part was the weather station display. After some googling discovered some information regarding intercepting/decoding  Oregon Scientific Wireless Weather Station sensor data.

Notes:

Salvaged the 433Mhz receiver from the broken Oregon Scientific Wireless Weather Station. Decided to use the Arduino Wireless Weather Station & Web Server sketch by Chris Wicks 2011/12, but only used the necessary code to receive and decode the Oregon Scientific Wireless Weather Station data. Uploaded the modified sketch to the Arduino UNO, and Wow it worked the first time, was able to receive Oregon Scientific THGR266 Thermo-Hygro sensor data.
