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.
