Printed circuit board for passive infrared motion detector, has daylight sensor with wires that are bent around specific degrees opposite to surface of board, and tilted mirror fastened on board that lowers optical path of daylight

摘要

The board has a pyroelectric infrared sensor that is bundled over an infrared lens system. A daylight sensor (8) forms a photoelectric switch to process a motion detector signal when a preset brightness level and/or a corresponding light value is undershot. Soldering wires (9) of the sensor (8) are bent around 90 degrees opposite to a surface of the board. A tilted mirror (11) is fastened on the board that lowers an optical path of the daylight occurring perpendicular to the direction of the surface of the board around 90 degrees in the direction of the sensor (8).
