Overview
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.A PIR detectorcombined with a fresnel lens
are mounted on a compact size PCB together with an analog IC,SB0081, and
limited components to form the module. High level output of variable
width is provided.
