|
||||
*
|
||||
* Ambient Weather TX-8300 (also sold as TFA 30.3211.02).
|
||||
* 1970us pulse with variable gap (third pulse 3920 us).
|
||||
* Above 79% humidity, gap after third pulse is 5848 us.
|
||||
* - Bit 1 : 1970us pulse with 3888 us gap
|
||||
* - Bit 0 : 1970us pulse with 1936 us gap
|
||||
* 74 bit (2 bit preamble and 72 bit data => 9 bytes => 18 nibbles)
|
||||
* The preamble seems to be a repeat counter (00, and 01 seen),
|
||||
* the first 4 bytes are data,
|
||||
* the second 4 bytes the same data inverted,
|
||||
* the last byte is a checksum.
|
||||
* Preamble format (2 bits):
|
||||
* [1 bit (0)] [1 bit rolling count]
|
||||
* Payload format (32 bits):
|
||||
* HHHHhhhh ??CCNIII IIIITTTT ttttuuuu
|
||||
* - H = First BCD digit humidity (the MSB might be distorted by the demod)
|
||||
* - h = Second BCD digit humidity, invalid humidity seems to be 0x0e
|
||||
* - ? = Likely battery flag, 2 bits
|
||||
* - C = Channel, 2 bits
|
||||
* - N = Negative temperature sign bit
|
||||
* - I = ID, 7-bit
|
||||
* - T = First BCD digit temperature
|
||||
* - t = Second BCD digit temperature
|
||||
* - u = Third BCD digit temperature
|
||||
* The Checksum seems to covers the 4 data bytes and is something like Fletcher-8.
