RAIN SENSOR DETECTION WITH MOTOR ALERT USING ARDUINO

 

 RAIN SENSOR INTERFACE USING ARDUINO 

 

 

🌧️ Rain Sensor Interface with Arduino – Short Note

Overview:

A Rain Sensor is used to detect the presence and intensity of rain. It is commonly used in weather monitoring systems, smart irrigation, and automatic wiper systems.

✅Working Principle:

  • The sensing pad detects water droplets.

  • When it rains, water bridges the conductive lines, reducing resistance.

  • The module outputs:

    • Analog signal (moisture level)

    • Digital signal (rain detected or not, based on threshold)

 

🔌Connection:

  • Rain Sensor Module (includes sensing pad and control board)

  • Arduino Board

  • Connecting Wires

📝 Sample Arduino Code:

int sensorPin = 8; // RAIN sensor output pin
int ledPin = 13; //MOTOR to indicate RAIN detection

void setup() {
pinMode(sensorPin, INPUT);
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}

void loop() {
int sensorValue = digitalRead(sensorPin);

if (sensorValue == LOW) {
digitalWrite(ledPin, HIGH);
Serial.println(“Rain Detected”);
} else {
digitalWrite(ledPin, LOW);
Serial.println(“No Rain”);
}

delay(1000); // Delay for readability
}

✅ Applications:

  • Smart irrigation systems

  • Weather stations

  • Automatic window and roof systems

  • Wiper automation in vehicles
