Thierry Mugler wireless weather station decoder

Updated 18 may 2013

I own a Thierry Mugler wireless weather station with an outdoor temperature sensor.

Roel Reijerse reverse engineered the wireless weather station protocol and I ported it to Arduino Uno.

I connected a 433MHz receiver (SZSAW CZS-3) on digital pin 2

Download the code here.

I noticed after reset of the transmitter it transmits 5 times with 20 sec interval the following

1111 dddd tttt TTT 0 hhhh HHHH S 010 CCCCCCCC 1111

And after that it transmits with 60 sec interval.
