Water Level Control Berbasis Arduino

Water Level Control Merupakan sebuah alat yang dapat mengontrol ketinggiam/level air secara otomatis yang diukur oleh sensor ultrasonik.

Script program :

#define echoPin 11 

#define trigPin 10 

#define LEDPin 6 

#define  pompa 7

int maximumRange = 200;

int minimumRange = 0; 

long duration, distance; 

void setup() {

Serial.begin (9600);

pinMode(trigPin, OUTPUT);

pinMode(echoPin, INPUT);

pinMode(LEDPin, OUTPUT);

pinMode(pompa,OUTPUT);

}

void loop() {

digitalWrite(trigPin, LOW);

digitalWrite(pompa,LOW);

delayMicroseconds(2);

digitalWrite(trigPin, HIGH);

digitalWrite(pompa,HIGH);

delayMicroseconds(10);

digitalWrite(trigPin, LOW);

duration = pulseIn(echoPin, HIGH);

distance = duration/58.2;

if (distance >= maximumRange || distance <= minimumRange)

{

Serial.println("-1");

digitalWrite(LEDPin, HIGH);

digitalWrite(pompa,HIGH);

}

else {

Serial.println(distance);

digitalWrite(LEDPin, LOW);

digitalWrite(pompa,LOW);

//waktu tunda 50mS

delay(1000);

}

}
