|
* Help
|
|
* https://github.com/merbanan/rtl_433/blob/master/src/devices/infactory.c
|
|
*
|
|
* Analysis using Genuino (see http://gitlab.com/hp-uno, e.g. uno_log_433):
|
|
* Observed On-Off-Key (OOK) data pattern:
|
|
* preamble syncPrefix data...(40 bit) syncPostfix
|
|
* HHLL HHLL HHLL HHLL HLLLLLLLLLLLLLLLL (HLLLL HLLLLLLLL HLLLL HLLLLLLLL ....) HLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL
|
|
* Breakdown:
|
|
* - four preamble pairs '1'/'0' each with a length of ca. 1000us
|
|
* - syncPre, syncPost, data0, data1 have a '1' start pulse of ca. 500us
|
|
* - syncPre pulse before dataPtr has a '0' pulse length of ca. 8000us
|
|
* - data0 (0-bits) have then a '0' pulse length of ca. 2000us
|
|
* - data1 (1-bits) have then a '0' pulse length of ca. 4000us
|
|
* - syncPost after dataPtr has a '0' pulse length of ca. 16000us
|
|
* This analysis is the reason for the new r_device definitions below.
|
|
* NB: pulse_slicer_ppm does not use .gap_limit if .tolerance is set.
|
|
*
|
|
* Outdoor sensor, transmits temperature and humidity data
|
|
* - inFactory NC-3982-913/NX-5817-902, Pearl (for FWS-686 station)
|
|
* - nor-tec 73383 (weather station + sensor), Schou Company AS, Denmark
|
|
* - DAY 73365 (weather station + sensor), Schou Company AS, Denmark
|
|
* Known brand names: inFactory, nor-tec, GreenBlue, DAY. Manufacturer in China.
|
|
* Transmissions includes an id. Every 60 seconds the sensor transmits 6 packets:
|
|
* 0000 1111 | 0011 0000 | 0101 1100 | 1110 0111 | 0110 0001
|
|
* iiii iiii | cccc ub?? | tttt tttt | tttt hhhh | hhhh ??nn
|
|
* - i: identification; changes on battery switch
|
|
* - c: CRC-4; CCITT checksum, see below for computation specifics
|
|
* - u: unknown; (sometimes set at power-on, but not always)
|
|
* - b: battery low; flag to indicate low battery voltage
|
|
* - h: Humidity; BCD-encoded, each nibble is one digit, 'A0' means 100%rH
|
|
* - t: Temperature; in °F as binary number with one decimal place + 90 °F offset
|
|
* - n: Channel; Channel number 1 - 3
