Passive Infrared (PIR) Motion Sensor | Electronics Byte

How Science Can Help You Open a Locked Door! A passive infrared (PIR) motion sensor is an electronic device that detects motion by sensing changes in infrared radiation, primarily emitted by warm objects like humans and animals. Unlike active sensors, PIR sensors do not emit any signals; instead, they passively detect infrared radiation through two or more pyroelectric elements that generate a voltage when they detect changes in radiation levels. Typically, these sensors have a detection range o

PIR via a Contactor Large Load - Wiring Diagram Part 4 Matt looks at the basic wiring diagram for a circuit controlled by a Passive infrared sensor (PIR) switching a contactor controlling a large load heavy load). He looks at the working principles for controlling a circuit by a remote PIR to control things such as lights. In part one Matt looks at the wiring connections in both the PIR's and the use of a contactor to switch the load circuit is via two circuit breakers (CB) This On Site with Mat
