WATERPUMP AUTO SWITCH

As we know that storing water into a storage tank is a way to save energy and the pump’s life than the pump turn on every time when we open the water tap.

In this project we show how to use simple way to switch on the pump automatically to fill the water tank when the water in the tank reaches the minimum limit, then the pump will turn off automatically when the water in the tank reaches the maximum limit.

The similar thing you can see on https://arduinoproyek.wordpress.com/2019/05/15/water-level-controlled-by-ip67-sensor/

Water pump auto switch

#define led 11 //this pin for drive relay

void setup() {

Serial.begin(9600);

pinMode(led, OUTPUT);

}

void loop() {

int sensorValue0 = analogRead(A0);

int sensorValue1 = analogRead(A1);

if (sensorValue0 <= 500) {

digitalWrite(led, LOW);//this output go to relay IN

}

if (sensorValue1 >= 500) {

digitalWrite(led, HIGH);

}

Serial.print(sensorValue0);

Serial.print(” “);

Serial.println(sensorValue1);

delay(100);

}
