Hc-sr501 sensor pir ajustable para arduino

Especificaciones

(PIR) Passive Infra-Red sensors are used to detect motion based on the infrared heat in the surrounding area. This makes them a popular choice when building a system to detect potential intruders or people in general. These sensors can take for 10-60 seconds to warm up, Also You can change the delay adjustment and sensitivity adjustment by changing the value of capacitors

SAMPLE CODE

// (HC-SR501) PIR Sensor

int PIRpin = 8; // PIR connected pin
int value;

void setup() {
Serial.begin(9600);
pinMode(2, OUTPUT); //For Led
}

void loop() {
value = digitalRead(PIRpin); //Read PIR state

if (value == LOW) {
Serial.println("No Movement");
digitalWrite (2, LOW);
}
else {
Serial.println("Movement!");
digitalWrite (2, HIGH);

}

delay(100); //Wait
}
