Abstract
A temperature and passive infrared sensor module comprising a sensor module housing having air flow vents therein in top and bottom or side surfaces to allow air to circulate through the sensor module housing. A temperature sensor is mounted in the sensor module housing in a position which is exposed to air circulating through the sensor module housing. A passive infrared sensor is also mounted in the sensor module housing in a manner in which it is not exposed to air circulating through the sensor module housing, such that it is not adversely affected thereby. In one embodiment, a foam block is positioned around to encase and isolate the passive infrared detector. In several embodiments, the passive infrared sensor and temperature sensor are mounted on opposite sides of the printed circuit board such that air circulates around the temperature sensor only on one side of the printed circuit board. In other embodiments, the passive infrared sensor and temperature are positioned on the same side of a printed circuit board, and a partition is positioned therebetween to prevent air circulating around the temperature sensor from reaching and circulating around the passive infrared sensor.
