Passive Infrared Sensor (PIR) Module: Detects motion using a pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens.
Motion Detection: Capable of sensing movement of people, animals, or objects within its detection range.
Common Terms: Also known as “Pyroelectric”, “Passive Infrared”, and “IR Motion” sensor.
Applications: Widely used in burglar alarms and automatically-activated lighting systems for enhanced security and convenience.
Pyroelectric Sensor: Detects changes in infrared radiation emitted by objects in its field of view, triggering the sensor.Fresnel Lens: Enhances the sensor’s sensitivity by focusing infrared radiation onto the pyroelectric sensor.
Versatile Usage: Suitable for various indoor and outdoor applications where motion detection is required for automation and security purposes.
