Digital PIR Motion Sensor -Arduino Compatible

This module can be used with Arduino Special Sensor Shield V4.0.
You can do some simple design about it，it support“plug and play”。

PIR motion sensing Brick

This brick includes a PIR motion sensor module,Max sentry distance is 3 and 7 meters. If anyone moved in that range, Alarm pin will go high. The signal duration can be adjusted from 0.3s-18s by the yellow potienmeter.

This PIR Sensor Switch Module detects the Infrared Rays released by human body motion within the detection area (6 Meters/20 feet).

PIR Sensor : A PIR Sensor is a Passive Infrared Sensor which controls the switching on/off when it detects a moving target. The PIR Sensor senses the motion of a human body by the change in surrounding ambient temperature when a human body passes across.

Delay Time Adjustable: 5 seconds to 18 Minutes.

Once the motion is seized , it sends a “low” digital value to the Arduino through the digital IO port of Sensor Shield
 

the corresponding Arduino code is :

int ledPin = 13;
int switchPin = 2;
int value = 0;

void setup() {
  pinMode(ledPin, OUTPUT);
  pinMode(switchPin, INPUT);
}

void loop() {
  value = digitalRead(switchPin);
  if (HIGH == value) {
    digitalWrite(ledPin, HIGH);
  } else {
    digitalWrite(ledPin, LOW);
  }
}
