Infrared Sensors Overview: Types, Functioning and Use ...

2019-07-29· Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).

How UV, IR and Imaging Detectors Work - Sensor Technology

The IR sensor is curbed to keep a “reasonable” activation of the IR chain by the surrounding thermal background. By using extra information in the IR band, via a second sensor, this increases the gain of the amplification chains of the detector and thus increases the detection range, and at the same time maintains a good immunity to false alarms.
