Infrared PIR Sensor, a Passive Infrared Sensor.&lt;br /&gt;
&lt;br /&gt;
It detects objects within its range that emit infrared radiation.&lt;br /&gt;
&lt;br /&gt;
It can detect the faint infrared radiation emitted by humans, and allows for adjustments in detection distance and delay time.&lt;br /&gt;
&lt;br /&gt;
== &amp;#039;&amp;#039;&amp;#039;Specifications&amp;#039;&amp;#039;&amp;#039; ==&lt;br /&gt;
&lt;br /&gt;
* Operating Voltage: 4.5V ~ 20V&lt;br /&gt;
* Quiescent Current: 50uA&lt;br /&gt;
* Detection Angle: 110 degrees&lt;br /&gt;
* Delay Time: 3 seconds ~ 300 seconds&lt;br /&gt;
* Detection Distance: 3m ~ 7m&lt;br /&gt;
&lt;br /&gt;
== &amp;#039;&amp;#039;&amp;#039;Required Hardware&amp;#039;&amp;#039;&amp;#039; ==&lt;br /&gt;
&lt;br /&gt;
* Infrared Human Body Motion Sensor&lt;br /&gt;
* Arduino&lt;br /&gt;
&lt;br /&gt;
== &amp;#039;&amp;#039;&amp;#039;Connection&amp;#039;&amp;#039;&amp;#039; ==&lt;br /&gt;
The following is the circuit used in the example code.&lt;br /&gt;
&lt;br /&gt;
If using the Infrared Human Body Motion Sensor by itself, an LED is not necessary.&lt;br /&gt;
&lt;br /&gt;
Instead of an LED, other modules can be applied and utilized.&lt;br /&gt;

== &amp;#039;&amp;#039;&amp;#039;Example Code&amp;#039;&amp;#039;&amp;#039; ==&lt;br /&gt;
This is an example that uses the Infrared Human Body Motion Sensor to light up an LED.&amp;lt;syntaxhighlight lang=&amp;quot;c++&amp;quot; line=&amp;quot;1&amp;quot;&amp;gt;&lt;br /&gt;
#define PIR 7     //Define motion sensor pin&lt;br /&gt;
#define LED 8     //Define LED pin for verification&lt;br /&gt;
int state = 0;     //Variable for storing state&lt;br /&gt;
void setup()&lt;br /&gt;
{&lt;br /&gt;
  pinMode(PIR, INPUT);&lt;br /&gt;
  pinMode(LED, OUTPUT);&lt;br /&gt;
  digitalWrite(LED, LOW);&lt;br /&gt;
}&lt;br /&gt;
&lt;br /&gt;
void loop(){      //Code to light up the LED when motion is detected&lt;br /&gt;
//  state = digitalRead(PIR);&lt;br /&gt;
  if(digitalRead(PIR))&lt;br /&gt;
  {&lt;br /&gt;
    digitalWrite(LED, HIGH);&lt;br /&gt;
    delay(1000);&lt;br /&gt;
  }&lt;br /&gt;
  digitalWrite(LED,LOW);&lt;br /&gt;
}&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&lt;br /&gt;
