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.
