such as burglar alarm, automatic light control, automatic valves and the like. CdS photoresistor light resistance should be selected (brighter environment at the resistance) is less than l00k, dark resistance is greater 3.3M products. Pyroelectric infrared sensor PIR can choose any of a small pyroelectric sensor (bring along a lens, such as ANM1 type).
