The ScopeDome Cloud Sensor is a cloud and rain sensor based on sky temperature measurement, dedicated to work with the ScopeDome Arduino card. It allows for the automatic closing of the dome in case of rain or cloud cover. The built-in sensor heating system prevents false alarms caused by dew.

Important: for proper operation of cloud sensing feature it is necessary to add a ScopeDome Thermometer Probe for external temperature sensing to our Arduino card. It should be connected to Ow2 input of the card.
