2. Passive infrared sensor - Wikipedia

   en.wikipedia.org/wiki/Passive_infrared_sensor

   A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.

3. Motion detector - Wikipedia

   en.wikipedia.org/wiki/Motion_detector

   A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.

4. Occupancy sensor - Wikipedia

   en.wikipedia.org/wiki/Occupancy_sensor

   Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.

5. Camera trap - Wikipedia

   en.wikipedia.org/wiki/Camera_trap

   A camera trap with a passive infrared (PIR) sensor. A camera trap is a camera that is automatically triggered by motion in its vicinity, like the presence of an animal or a human being. It is typically equipped with a motion sensor—usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam. [1]

6. Infrared detector - Wikipedia

   en.wikipedia.org/wiki/Infrared_detector

   Prototype of high-speed infrared detector installed on the PIONIER instrument at ESO’s Paranal Observatory. [1]An infrared detector is a detector that reacts to infrared (IR) radiation.
