WANDERERBOX ULTIMATE ENVIRONMENT SENSOR

The Wanderer Astro Environment Sensor for the Wandererbox Ultimate control unit allows you to remotely monitor the ambient humidity and temperature levels for automatic control of dew heater power. 

Note: Wanderer Astro also sells an temperature sensor for monitoring of the temperature of the dew heaters for automatic control of their power. Only one of these can be used at a time as they use the same single port on the Wandererbox Ultimate, so you do not need to purchase both.
