KCB Datasheet pdf – Master PIR control chip (MPCC) – COMedia Ltd

F Internal switched capacitor bandpass filter reduces external component count and improves reliability by.

Adjustable OFF timer activates whenever motion stops.

M Four main operating modes can be used in any combination: Pin 8 Pyro S is a sensitive node and the external interconnect to this pin should be made as short dwtasheet possible. Load turns on manually, with a momentary contact switch. If the load goes off because you stopped moving reading a book for exampleyou have 6 seconds to wave your arm to turn the load back on.

Daylight detector can be disabled. If the load goes off because you stopped moving reading a book for. The MPCC has been designed for easy implementation. Adjustable daylight detector disables Auto-ON during daytime. F Internal switched capacitor bandpass filter reduces external component count and improves reliability by minimizing sensitivity to external component values. E Adjustable PIR sensitivity. I Daylight detector circuitry is designed to use either silicon photo diode or CdS detector.

Ozitronics – Security

Load turns off if there is no motion during the time delay. A Circuit design maximizes performance while minimizing external component count and board layout space. Load turns off manually, with a momentary contact switch. H High immunity to line frequency noise.

Due to its high sensitivity and reliability, it is also widely used in security product. If Datashert mode is disabled, the load will turn on if there is motion within 6 seconds after turn-off. Auto-ON mode can be disabled. Load turns off manually, with a momentary contact switch. A Circuit design maximizes performance while minimizing external component count and board layout space.

H High immunity to line frequency noise. M Four main operating modes can be used in kc778g combination: Due to its high sensitivity and.

This node should also be closely surrounded by a ground plane. J Adjustable daylight detector sensitivity. Load turns on when motion is detected adjustable sensitivity. Load turns on when motion is detected adjustable sensitivity. The value of the pot is not critical and any value between E Adjustable PIR sensitivity. If Auto-ON mode is disabled, the load will turn on if there is motion within 6 seconds.

C High sensitivity PIR input with special noise cancellation circuitry.
