Introduction

HC-SR505 Mini PIR Motion Sensor is based on infrared technology and it can automatic control by itself with high sensitivity and high reliability. Because of the minimum size and low-power operation mode, it widely used in various of automatic electronic equipment, especially battery-powered automatic products.
Module:SPS50506S

Usage

Hardware

Connect the PIR Motion Sensor to your Arduino/Crowduino power supply pin and digital pins. You can can connect the "s" terminal to any of your arduino Pins,like the "D6" as belows:

Programming

1.Copy the following program to Arduino IDE and upload to your Arduino/Crowduino:

void setup()  {
  Serial.begin(9600);
  pinMode(6,INPUT);
  digitalWrite(6,LOW);
}
void loop()  {
    if(digitalRead(6)==HIGH)  {
      Serial.println("Somebody is here.");
    }
    else  {
      Serial.println("Nobody.");
    }
    delay(1000);
}

2.Open the Serial moniter , and set the baudrate to 9600, you will see that When somebody is in front of the sensor , the Serial Monitor will output "Somebody is here.".Or, the Serial Monitor output "Nobody."
