Finally it is time to introduce the snow height measurement system officially.

  • Automatically measures snow height with a laser range meter
  • Emulates a HTU temperature sensor to transmit snow height as humidity value
  • Snow height can be mapped on the RX station to an extra humidity to get it to any weather software

Supported devices:
  • HIREED Laser ranging device with rs232 interface
    (can be bought on AliExpress or Ebay)
  • HOLO Laser ranging device
    (can be bought as bundle including the PCB)

Hello Zdenek,

thank you for your answer. Very interesting paper and very interesting that I made similar experiences in the last years.

For tonight some snow is announced, so im looking forward to check what the sensor will read tomorrow.

Best regards,
Tuesday the snow height measurement registered the first bit of snow for this season  Smile .

See the temperature, the total counts of the tipping bucket and the snow height in the diagramm.
Everything still seems to work properly.
