Circuit is formed mainly by the new pyroelectric infrared sensor TDH98072. The circuit assembled with the device is of the advantages like simple circuit, easy adjustment, and high reliability. The device can also assemble other control circuits, such as burglar alarm, automatic lights, automatic valves, etc.The light resistance (in the bright environment resistance) of the selected CdS photoresistor should be less than l00kΩ,and dark resistance should be greater than 3.3MΩ. Pyroelectric infrared sensor PIR can choose either a small pyroelectric sensor (with the lens, such as ANM1 type).
