Description

This is HC-SR501 IR Pyroelectric Infrared  Motion Sensor Detector Module

PIR sensors are used to detect motion from pets/humanoids from about 7m away. This one has an adjustable delay before firing (approx 2-4 seconds), adjustable sensitivity.

  • working voltage range :DC 4.5-20V
  • Quiescent Current :50uA
  • high output level 3.3 V / Low 0V
  • Trigger L trigger can not be repeated / H repeated trigger
  • circuit board dimensions :32 * 24 mm
  • maximum 110 ° angle sensor 7.
  • 7 m maximum sensing distance

Getting started with PIR Motion sensor

In this project you’re going to create a simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected.

Parts required

Connecting the Hardware

Tx: Adjust the duration of the HIGH output. The shortest time is about 3 seconds and the longest is about 5 minutes. Turning the potentiometer clockwise increases the time and turning it counter-clockwise decreases the time.

Sx: Adjust the sensitivity, or range, of the sensor . The sensor can detect motion in a range from as close as 2 meters up to 7 meters. Turning the Sx potentiometer clockwise decreases the range and turning it counter-clockwise increases the range.

Setting the trigger jumper

With this jumper you can select the mode of the module.

Single trigger(H):

The output pulse starts immediately after a movement is detected and remains ‘H‘ until the set time has elapsed. If during this time other motion detections occur, they have no influence.

Repeatable trigger (L):

Every new movement detected starts a new time cycle.

Connect your Motion sensor to Arduino Uno as shown bellow.

  • GND: GND
  • VCC: 5V
  • Out: D2 (you can choose yours)
  • LED: D13 (you can choose yours)

Uploading the Codes

Upload the following code into your Arduino.

//In this tutorial we have set our trigger jumper to 'H'
int sensorPin = 2; //sensor on digital pin
int LED = 13; //LED on digital pin

void setup() {
pinMode(sensorPin, INPUT);
pinMode(LED, OUTPUT);
Serial.begin(9600); //boud rate
}

void loop() {
int val = digitalRead(sensorPin);
digitalWrite(LED, val);
if(val==1)Serial.println("\tMotion Detected.");
else Serial.println("\tNo motion detected.");
delay(100);
}
