Description

  • The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects.
  • This motion can be detected by checking for a sudden change in the surrounding IR patterns.
  • When motion is detected the PIR sensor outputs a high signal on its output pin.
  • This logic signal can be read by a microcontroller or used to drive a transistor to switch a higher current load.
