StellarMate Pro Temperature & Humidity Sensor
Connect the SM Pro Temperature & Humidity sensor to your SM Pro AUX port to receive highly accurate measurements for temperature and relative humidity. The sensor can be used for a variety of applications, but most notably, it is critical for SM Pro's Auto Dew feature to work. Place the probe close to the OTA and away from the unit. Make sure the TRRS connector is fully inserted in the AUX port.
