6. Sensor Gerak(PIR)

//Sensor PIR, output ---|____  HIGH-LOW seting Delay_Time minimal
//setelah mendeteksi gerakan output HIGH selama 1,8S
//setelah 1,8S akan menjadi LOW selama 6S sebelum mendeteksi gerakan baru

volatile boolean dataPIR;
int temp;
int temp1;

void setup()
{
  Serial.begin(9600);
  pinMode(A0, INPUT);
  dataPIR=0;
}

void loop(){
    dataPIR = digitalRead(A0);

    //mendeteksi ada gerakan
    if (dataPIR==1){
      if (temp1==1){
        Serial.println("PIR mendeteksi ada gerakan:");
        //tuliskan program dibawah ini, ketika mendeteksi gerakan:
        
        
        }
      delay(100);temp1 = temp1 + 1;
      
      if (temp1%10==0) {
        Serial.print("HIGH:");
        Serial.println(temp1);}
      }

    //lama waktu LOW, sebelum bisa mendeteksi gerakan baru
    if (temp<=70) {              //counter menghitung 7 detik
      delay(100);temp = temp + 1;
      
      if (temp%10==0) {
        Serial.print("LOW:");
        Serial.println(temp);}
        if (temp==70){Serial.println("PIR siap merespon gerakan baru:");}
      }

    if (dataPIR==0){temp1=0;}   //reset counter
    if (dataPIR==1){temp=0;}    //reset counter jika ada gerakan
