PIR 센서는 모션을 감지할 수 있는 기능이 있습니다. 

자판기 앞을 지날 때, LED 등이 켜지는 것 혹은 불이 꺼진 화장실에 들어가는 순간 불이 켜지는 등의 동작을 요구할 때 사용될 수 있고, 널리 사용되고 있는 제품이기도 합니다. 

적외선을 넓게 퍼트리는 방식으로 인식하며 모듈화가 되어있어 디지털 신호로 값을 출력합니다.


특징

입력 전압 : 3.3 ~ 5V, 최대 6V

동작 전류 : 15uA

동작 온도 : -20 ~ 85도

출력 전압 : HIGH 3V, LOW 0V

출력 지연 시간 : 2.3 ~ 3초

인식 각도 : 100도

인식 거리 : 7m

크기 : 30 x 22mm

INTRODUCTION

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

This PIR (Motion) Sensor can detect the infrared signals from human body or other animals and triggers with movement. So it can be applied to a variety of scenarios which require motion detection. Conventional pyroelectric infrared sensors require body pyroelectric infrared detector, integrated chipsets, complex peripheral circuit. So the size is slightly big, circuit is complex, and reliability is slightly lower. We bring this new pyroelectric infrared motion sensor which is specially designed for your Arduino projects, an integrated digital body pyroelectric and infrared sensor, with small size, high reliability, low power consumption, and simple peripheral circuit. Very simple to use in any project.
