Description of PIR Motion Sensor Module
Quick Overview
The PIR (Passive Infrared) Motion Sensor Module is designed to detect the motion of humans or animals within its sensing range by picking up infrared radiation emitted by them. It is widely used in security systems, automation, and interactive projects, offering a simple yet effective way to detect movement.
How It Works
The PIR Motion Sensor Module contains a pyroelectric sensor that detects the infrared radiation emitted by a moving object (e.g., a human or animal). When the sensor detects a change in the amount of infrared radiation within its field of view, it triggers a digital output signal. Basic Functioning involves: Sensing infrared radiation through the pyroelectric sensor. Comparing the current reading with previous readings to detect changes. Triggering a digital output if a significant change in radiation is detected. The module can interface easily with microcontrollers like Arduino or Raspberry Pi using a digital I/O pin.
