Seeed Studio 101020793 - Grove - Digital PIR Motion Sensor(12m)

Description

This Grove Digital PIR Sensor is the cheapest PIR sensor in the PIR families, however, it is able to give a quick response and generate a high signal from the "sig" Pin.

Features

  • Quick response: detect motion and output with only ‘high’ and ‘low’ digital signals less than 1s
  • Wide detection range: 3.2m-12m
  • Easy to use: Grove compatible interface and supports both Arduino and Raspberry Pi platforms

What is a PIR Sensor?

A passive infrared sensor is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications.

What does a PIR sensor detect?

PIR sensors are also known as PID or Passive Infrared Detectors. Thus, the PIR sensor can detect infrared radiation that is emitted by particles.

How does PIR Sensor work?

The PIR Sensor has 2 slots, and the slots are made of sensitive material. When the sensor is inactive, then the two slots will sense the same amount of IR. The ambient amount radiates from the outdoors, walls or room, etc.
When a human body or any animal passes by, it intercepts the first slot of the PIR sensor. This causes a positive differential change between the two bisects. But when the body leaves the sensing area, the sensor generates a negative differential change between the two bisects.
