Introduction

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.

Sample Code

const int buttonPin = 2;

const int ledPin =  13;

void setup() {

pinMode(ledPin, OUTPUT);

pinMode(buttonPin, INPUT);

}

void loop()

{

if (digitalRead(buttonPin) == HIGH)

{

digitalWrite(ledPin, HIGH);

}

else {

digitalWrite(ledPin, LOW);

}

}

Result

When sensors detect people closed, the light will be lighted.
