DM produces I2C temperature probes. These can be connected to the SensorNode to read temperature at regular intervals.

DM temperature probes use the following wiring colours:

• Red = Positive - connect to 3.3V
• Brown = Clock - connect to SCL
• Orange = Data - connect to SDA
• Black = Ground - connect to GND

New DM Temp Sensor:

In 2018 we introduced a new temperature sensor that allows you to set the address to Address 1 or Address 2:

• Address 1 (DM Temp Sensor 1): Green - connect to ground
• Address 2 (DM Temp Sensor 2): Green - connect to 3.3V
• The rest of the wiring stays the same
