Infrared (IR) Presence Sensors on Swinging Doors:

How the sensors work – Sensors belonging to the group, or class, that exhibits the subject design flaw are mounted physically on the swinging door panel and transmit near-infrared light (typically at a peak wavelength of between 880 and 950 nm, and invisible to the human eye) into the volume of space immediately adjacent to the sensor and, hence, the door.

What is an IR sensor? | FierceElectronics

29-07-2019· An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the ...

Understanding Active & Passive Infrared Sensors …

11-09-2018· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies ...
