• Size: Ф 11.8MM
• Focal length: 5MM
• Thickness: 0.6MM
• Material science: HDPE
• Response angle: 120 degrees
• Response distance: 5m
• Operating voltage 5v

Upload the CODE

int led = 13; // the pin that the LED is atteched to
int sensor = 2; // the pin that the sensor is atteched to
int state = LOW; // by default, no motion detected
int val = 0; // variable to store the sensor status (value)

void setup() {
pinMode(led, OUTPUT); // initalize LED as an output
pinMode(sensor, INPUT); // initialize sensor as an input
Serial.begin(9600); // initialize serial
}

void loop(){
val = digitalRead(sensor); // read sensor value
if (val == LOW) {
digitalWrite(led, HIGH);
delay(100);

if (state == HIGH) {
Serial.println(“Motion detected!”);
state = LOW;
}
}
else {
digitalWrite(led, LOW);
delay(1000);

if (state == LOW){
Serial.println(“Motion stopped!”);
state = HIGH;
}
}
}

RESULTS

A LED will light up when movement is detected and the serial monitor prints “Motion detected!”
