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
