Some time ago I decoded the transmission of an ACURITE W091 Temperature Sensor, also 433 MHz and it seems to use a similar protocol. The bit coding certainly seems to be the same. I used a 433 MHz receiver, the line audio in jack and Audacity on a laptop to capture the signal. My notes indicate the following:
9 milliseconds start bit
4 milliseconds RF off = 1 bit
2 milliseconds RF off = 0 bit
Transmissions: 9 ms start bit, followed by 24 bits repeated 11 times
each 24 bit packet consists of 10 bit sensor ID, 12 bits temperature in degrees C*10, then two bits of unknown function. Negative temperature is stored as 2's complement.
The sensor ID is a rolling code and changes every time you disconnect and reconnect the battery.
The WxShield software mentioned in a previous post doesn't appear to decode this particular sensor. I spent some time looking at your data but am stumped. I like a challenge, so more examples with different values would help! Please let us know how you finally decode your transmissions.
