PIR Motion Sensor
Quick Instructions
Version: 2
Delivery Content
- Module
Description
The module is a Passive Infrared Sensor that detects motion. Use HIGH and LOW signals to make decisions in your project. Use the adjustment dials to adjust sensitivity and delay (see Specifications section for details).
Pinout / Pin Map
| Pin | Description |
| OUT | LOW or HIGH signal when motion is detected |
| VCC | Power |
| GND | GND |
Example Application
The example makes a connected LED light up when motion is detected.
The instructions use the Arduino® platform to illustrate product use. You can also use an Arduino derivative or another platform that supports this type of product.
Connection
| Module | OU | VCC | GND |
| Arduino® | 2 | 5V | GND |
Code
const int PIRSensor = 2;
const int ledPin = 13;
int sensorValue = 0;
void setup() {
pinMode(PIRSensor, INPUT);
pinMode(ledPin, OUTPUT);}
void loop(){
sensorValue = digitalRead(PIRSensor);
if (sensorValue == HIGH) {
digitalWrite(ledPin, HIGH);}else {
digitalWrite(ledPin, LOW);}}
Procedure
- Prepare a sketch with the given code and upload it to your board.
- Connect the module/component to the board as shown in the connection diagram or table.
- Connect an LED to pin 13.
- When motion is detected the LED goes on.
