Infrared Digital PIR Motion Sensor
We can build electronics projects just as easy as piling bricks. Arduino and community have made the programming much easier than ever before. How about some elixir on hardware part? Maybe it is not yet convenient to make complex interfaces, but we can at least start from the most commonly used modules.
By using electronic bricks, you may connect Arduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos...even buttons, just plug and play.
Each terminal module has buckled port with VCC, GND and Output, which has corresponding port on the sensing board, with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.
It is very interesting Electronic Brick Module
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
Connect the signal cables and Arduino port , then it can be used:
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);
}
}

This sensor module come with 3 Pin Dual-female Jumper Wire length 300mm as below :
