* Acurite 592TXR Temperature Humidity sensor decoder
|
|
* Message Type 0x04, 7 bytes
|
|
* | Byte 0 | Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 |
|
|
* | --------- | --------- | --------- | --------- | --------- | --------- | --------- |
|
|
* | CCII IIII | IIII IIII | pB00 0100 | pHHH HHHH | p??T TTTT | pTTT TTTT | KKKK KKKK |
|
|
* - C: Channel 00: C, 10: B, 11: A, (01 is invalid)
|
|
* - I: Device ID (14 bits)
|
|
* - B: Battery, 1 is battery OK, 0 is battery low
|
|
* - M: Message type (6 bits), 0x04
|
|
* - T: Temperature Celsius (11 - 14 bits?), + 1000 * 10
|
|
* - H: Relative Humidity (%) (7 bits)
|
|
* - K: Checksum (8 bits)
|
|
* - p: Parity bit
|
|
* Notes:
|
|
* - Temperature
|
|
* - Encoded as Celsius + 1000 * 10
|
|
* - only 11 bits needed for specified range -40 C to 70 C (-40 F - 158 F)
|
|
* - However 14 bits available for temperature, giving possible range of -100 C to 1538.4 C
|
|
* - @todo - check if high 3 bits ever used for anything else
|
