Grove - PIR Motion Sensor

Grove - PIR Motion Sensor

Denna sensor gör att du kan känna rörelse, vanligtvis mänsklig rörelse inom sitt område. När någon rör sig i sitt detekteringsområde, kommer sensorn att mata HIGH på sin SIG-stift.

Kompatibilitet

• Arduino
• Raspberry Pi

Port

• Digital

Exempelkod

Arduino

#define PIR_MOTION_SENSOR 2//Use pin 2 to receive the signal from the module
void setup()
{
    pinMode(PIR_MOTION_SENSOR, INPUT);
    Serial.begin(9600);  

}
void loop()
{
    if(digitalRead(PIR_MOTION_SENSOR)) {//if it detects the moving people?
        Serial.println("Hi,people is coming");
    } else {
        Serial.println("Watching");
    }
    delay(200);
}

Raspberry Pi

import time
import grovepi

# Connect the Grove PIR Motion Sensor to digital port D8
# SIG,NC,VCC,GND
pir_sensor = 8

grovepi.pinMode(pir_sensor,"INPUT")

while True:
    try:
        # Sense motion, usually human, within the target range
        if grovepi.digitalRead(pir_sensor):
            print 'Motion Detected'
        else:
            print '-'

        # if your hold time is less than this, you might not see as many detections
        time.sleep(.2)

    except IOError:
        print "Error"
