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.

StellarMate Pro Auto Dew

StellarMate Pro (SMP) can control up to two dew heaters. To enable auto-dew feature in SMP, use SM App Power tab to enable Auto Dew. The temperature, humidity, and dew point are displayed in the bottom-right corner of the page.

Set he desired duty cycle for each dew heater. Adjust the Dew Heater threshold in degrees celcius. When the difference between ambient temperature and the dew point is at or below this threshold then the dew heaters are automatically engaged.

For example, if the ambient temperature is 10C and dew point is 5C, then the difference is (Ambient - Dew Point) = 5C. If the threshold is set to 5C, then the dew heaters are engaged. When the difference is larger than threshold, the dew heaters are turned off.
