Summary

Adds support for Auriol HG02832 / HG05124A temperature and humidity sensors
to the Weather Station application.

The decoder supports:

  • sensor ID
  • channel
  • battery status
  • manual TX button
  • temperature
  • humidity
  • CRC validation

Protocol:

  • 433.92 MHz
  • OOK PWM
  • ~252 µs short pulse
  • ~612 µs long pulse
  • ~860 µs synchronization pulse
  • 40-bit payload

Testing

Tested on an original Auriol HG05124A-TX sensor.

Verified:

  • positive temperatures
  • negative temperatures
  • decimal temperatures
  • humidity
  • channel switching
  • repeated reception in Weather Station

The implementation was developed by analysing real RF captures from an
original sensor and validated against multiple real-world transmissions.
