The Cello Sensor is a Wi-Fi and BLE pocket size communication device. Other ports are available on the Cello sensor namely: HDMI, 10/100 Ethernet, and 1-wire for optionally connecting an external temperature sensor. The Cello Sensor has a built-in IR transceiver for commanding ductless, portable or window based AC and heat pumps and a RF motion sensor. Optionally, the user can add secondary BLE temperature sensors for better temperature tracking if the zone area is large.
