Widely used in human body sensor switch, alarm, infrared thermometer and infrared imaging and other aspects. It can provide users with different sensing angles, sensing distances, sizes, and test ratios. Fresnel lens function: first, focusing effect; The second is to divide the detection area into several bright and dark areas, so that the moving objects entering the detection area can produce a change pyroelectric infrared signal on the PIR (passive infrared detector) in the form of temperature changes.
