SensorNode: Wiring up a DM Temp/RH sensor

DM produces I2C temperature and relative humidity (RH) sensors. These are also known as "ambient sensors".

These can be connected to the SensorNode to read temperature and/or RH at regular intervals.


DM Temp/RH sensors use the following wiring colours:

  • Red = Positive - connect to 3.3V
  • Brown = Clock - connect to SCL
  • Green = Data - connect to SDA
  • Black = Ground - connect to GND
  • Purple = Not used.


To schedule this on the device, create a schedule item called "DM Ambient Sensor":
