RAIN DROP DETECTOR

 This project is used to detect wheather the rain is falling for not. You can use it for your science projects.

FOR VIDEO :

THING'S NEEDED

1. Arduino UNO R3
2. Rain Drop Sensor Module
3. 2 - LEDS
4. Buzzer

CIRCUIT DIAGRAM

WIRING

SENSOR TO ARDUINO

• Connect the Vcc Pin of sensor to 5V of Arduino.
• Connect the GND pin of sensor to GND of Arduino.
• Connect the AO (analogOutput) of sensor to pin A0 of Arduino.

LED & BUZZER TO ARDUINO

• Connect the Green LED to pin 2 of Arduino.
• Connect the Red LED to pin 3 of Arduino.
• Connect the Buzzer to pin 4 of Arduino.

// RAIN DETECTOR

int Sensor_IN = A0; // DEFINING INPUTS

int G_LED = 2; // DEFINING OUTPUTS

int R_LED = 3;

int Buzzer = 4;

// VARIABLE TO STORE SENSOR_IN ANALOG READING'S

int val;

  Serial.begin(9600); // STARTING SERIAL MONITOR

  pinMode(Sensor_IN , INPUT); // SETTING AS INPUT

  pinMode(G_LED , OUTPUT); // SETTING AS OUTPUT

  pinMode(R_LED , OUTPUT); // SETTING AS OUTPUT

  pinMode(Buzzer , OUTPUT); // SETTING AS OUTPUT

  

  // SETTING OUTPUT PIN TO LOW

  digitalWrite(G_LED ,LOW);

  digitalWrite(R_LED ,LOW);

  digitalWrite(Buzzer ,LOW);

}

void loop() {

  val = analogRead(A0);

  if (val < 500) {

    digitalWrite(G_LED , LOW);

    digitalWrite(R_LED , HIGH);

    digitalWrite(Buzzer , HIGH);

  }

  else {

    digitalWrite(G_LED , HIGH);

    digitalWrite(R_LED , LOW);

    digitalWrite(Buzzer , LOW);

  }
