PIR Movement Detectors: The movement detector detects infrared light that is emitted by
people and animals. Infrared light cannot be seen by human beings. However, the PIR
motion detector is equipped with an electronic infrared sensor that detects infared light.
When the infrared light changes, the PIR motion detector will apply specific algorithmic
calculations to help determine if the change in infrared light is indicative of a human being.
If so, it will emit a 433 MHz signal that is received by the Siren.
