How does the Aurora Cloud Sensor work?
This system works by comparing the sky temperature with the air temperature. Under clear skies the system senses the upper atmosphere temperature (which is very cold). However if the sky is cloudy the sky temperature is only slightly colder than the air temperature.

The system also has sensors for rain and light.
