PIR motion sensor

The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin. Module provides an optimized circuit that will detect motion up to 6 metres away and can be used in burglar alarms and access control systems.
