PIR Movement Detector
PIR Movement Detector
RE200B PIR Sensor used in Kit 30
Essential specs on RE200B sensor
Circuit designed around a recently developed movement IC the KC778B. Circuit utilizes PIR detector and a light dependent resistor (LDR) to provide an optimized circuit that will detect motion up to 6 metres away. Operates on 9-12 VDC. Note that the PIR sensor & the PCB-mounted fresnel lens fit on the other side of the PCB; the solder side. This is to allow the unit to be mounted inside a container with the detecting lens poking out and the controls facing inside the box
