A passive infrared sensor (PIR sensor) is an electronic device that measures infrared (IR) radiation emitted by objects in its field of view. They are most commonly used in motion detectors, including security alarms and automatic lighting systems.
The analysis highlights PIR-based motion detector, Overview and Operating principles as prominent areas in the source structure around Passive infrared sensor.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
