|
|
*
|
|
* Nexus sensor protocol with ID, temperature and optional humidity
|
|
* also FreeTec (Pearl) NC-7345 sensors for FreeTec Weatherstation NC-7344,
|
|
* also infactory/FreeTec (Pearl) NX-3980 sensors for infactory/FreeTec NX-3974 station,
|
|
* also Solight TE82S sensors for Solight TE76/TE82/TE83/TE84 stations,
|
|
* also TFA 30.3209.02 temperature/humidity sensor.
|
|
* The sensor sends 36 bits 12 times,
|
|
* the packets are ppm modulated (distance coding) with a pulse of ~500 us
|
|
* followed by a short gap of ~1000 us for a 0 bit or a long ~2000 us gap for a
|
|
* 1 bit, the sync gap is ~4000 us.
|
|
* The data is grouped in 9 nibbles:
|
|
* [id0] [id1] [flags] [temp0] [temp1] [temp2] [const] [humi0] [humi1]
|
|
* - The 8-bit id changes when the battery is changed in the sensor.
|
|
* - flags are 4 bits B 0 C C, where B is the battery status: 1=OK, 0=LOW
|
|
* - and CC is the channel: 0=CH1, 1=CH2, 2=CH3
|
|
* - temp is 12 bit signed scaled by 10
|
|
* - const is always 1111 (0x0F)
|
|
* - humidity is 8 bits
|
|
* The sensors can be bought at Clas Ohlsen (Nexus) and Pearl (infactory/FreeTec).
