Abstract:
A temperature and passive infrared sensor comprising:a. a sensor module housing having air flow vents therein to allow air to circulate through the sensor housing;b. a temperature sensor for detecting temperature;c. a passive infrared sensor for detecting passive infrared radiation;d. a printed circuit board defining a front electrical lead side, and an opposite back electrical component side, wherein the printed circuit board is positioned in the sensor module housing extending in a substantially vertical direction such that the printed circuit board defines upper and lower sections of both the front electrical lead side and the opposite back electrical component side thereof, the printed circuit board having heat generating electrical components mounted thereon on the back component side of the printed circuit board, and the temperature sensor and the passive infrared sensor are mounted on the front electrical lead side of the printed circuit board, such that the printed circuit board shields the temperature sensor and the passive infrared sensor from the heat generating components, and wherein the temperature sensor is mounted on a lower section of the electric lead side of the printed circuit board.
