12V DC SOLENOID VALVE

Introduction

A 12V Solenoid Valve is an electromechanical device used to control the flow of liquids or gases. It is commonly used in irrigation systems, water dispensers, and industrial automation. The valve opens or closes when a 12V DC signal is applied.

Working Principle

The solenoid valve contains an electromagnet and a plunger. When 12V DC is applied to the solenoid, the electromagnetic force pulls the plunger, allowing fluid or gas to flow through the valve. When the power is turned off, the spring pushes the plunger back to its original position, blocking the flow.

Arduino Control Example

const int solenoidPin = 7; // Solenoid connected to pin 7

void setup() {
    pinMode(solenoidPin, OUTPUT);
    Serial.begin(9600);
    Serial.println("Solenoid Valve Initialized");
}

void loop() {
    digitalWrite(solenoidPin, HIGH); // Open valve
    delay(5000);                     // Wait 5 seconds
    digitalWrite(solenoidPin, LOW);  // Close valve
    delay(5000);                     // Wait 5 seconds
}
