Product Description

This is a simple to use Arduino 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. This sensor checks for infrared heat in it’s detecting angle. The human body, pets and several other things emit energy that the sensor is looking for, it compares with the snapshot and if there is a recent change it triggers.Specification

Example Sketch & Diagram


int pirPin = 8;
int val;

void setup() {

void loop() {
  val = digitalRead(pirPin); //read state of the PIR
  if (val == LOW) {
    Serial.println("No motion"); //if the value read is low, there was no motion
  else {
    Serial.println("Motion!"); //if the value read was high, there was motion
