H High immunity to line frequency noise.

Load turns off if there is no motion during the time delay. I Daylight detector circuitry is designed to use either silicon photo diode or CdS detector. B Low cost solution for PIR motion control switching applications. The filter response can be measured in this way.

D Choice of two PIR gain settings: If the load goes off because you stopped moving reading a book for exampleyou have 6 seconds to dayasheet your arm to turn the load back on. Adjustable OFF timer activates whenever motion stops. The Sensitivity Adjust pot is used to select a voltage between the pyro drain reference voltage minimum sensitivity and Gnd maximum sensitivity. C High sensitivity PIR input with special noise cancellation circuitry.

K Adjustable OFF timer accuracy is determined by external components. Load turns on when motion is detected adjustable sensitivity. Auto-OFF mode can be disabled.
