The KSR501 PIR (Passive Infra Red) Module will find its way into security monitoring, point of purchase annunciators, patient activity monitoring, anti-collision detectors in corridors, alarm and evacuation advice units.
KSR501 PIR features a simplified input with only three wires. power supply and TTL compatible output.
Both repetition delay and sensitivity adjustments are fitted to the KSR501 PIR compact control board. One shot or repeat mode may be jumper selected.
