Abstract: A device may include a first infrared sensor, a second infrared sensor, a temperature detecting component, and an occupancy detecting component. The first infrared sensor may connect to the temperature detecting component through a first temperature signal path and the occupancy detecting component through a first occupancy signal path. The second infrared sensor may connect to the temperature detecting component through a second temperature signal path and the occupancy detecting component through a second occupancy signal path. The temperature detecting component may determine a temperature measurement by calculating an average of a value received from the first temperature signal path and a value received from the second temperature signal path. The occupancy detecting component may determine an occupancy measurement by calculating a difference of the value received from the first occupancy signal path and the value received from the second occupancy signal path.

Abstract: A device and system are disclosed for sensing ambient temperature. The device includes a housing having an exterior surface and an interior surface, a channel, formed through an opening in the housing from the exterior surface to the interior surface, a conductive element, thermally responsive to ambient air entering the channel, comprising an external surface and an internal surface, and a sensor situated within the housing and thermally coupled to the conductive element, wherein the sensor determines the ambient temperature of the device based at least on a detected temperature of the conductive element.
