|
|
* Humidity:
|
|
* - the working range is 20-90 %
|
|
* - if "LL" in display view it sends 10 %
|
|
* - if "HH" in display view it sends 110%

* TYP IIIIIIII BMCCTTTT TTTTTTTT HHHHHHHX XXXXX
|
|
* TYPE Description:
|
|
* - I = Random Device Code, changes with battery reset
|
|
* - B = Battery 0=OK 1=LOW
|
|
* - M = Manual Send Button Pressed 0=not pressed 1=pressed
|
|
* - C = Channel 00=CH1, 01=CH2, 10=CH3
|
|
* - T = Temperature, 12 Bit 2's complement, scaled by 10
|
|
* - H = Humidity = 7 Bit bin2dez 00-99, Display LL=10%, Display HH=110% (Range 20-90%)
|
|
* - X = Checksum, sum modulo 64
|
|
* A Lidl AURIO (from 12/2018) with PCB marking YJ-T12 V02 has two extra bits in front.
