Pyroelectric Infrared Motion Sensors & Fresnel Lens

Pyroelectric motion sensors may be used in a wide variety of applications. They are commonly found in security products, such as burglar alarms, motion detectors and intrusion detection systems. These sensors are also useful in environmental systems, lighting controls, visitor announcers, robotics, and artificial intelligence.They work by detecting the infrared heat emitted by the human body.
