Learn what triggers infrared sensors and how to optimize their performance.

80 views

Infrared sensors are triggered by heat sources like human bodies, animals, and warm objects. They detect infrared radiation emitted by these sources. Additionally, direct sunlight and certain electrical devices can also activate these sensors. To ensure optimal performance, keep sensors away from large heat-emitting objects and shield them from direct sunlight.
