ARDUINO WITH RAIN SENSOR

In this tutorial you will get to know that how you can create an rain water detection system .

Material requirements are given below :-

• RAIN SENSOR
• ARDUINO
• GREEN LED
• RED LED
• BRAEDBOARD
• JUMPER WIRES

Working

Whenever any water droplet is detected by the sensor red LED start glowing making you alert.

Otherwise green LED glows indicating no rain.

CONNECTIONS

ARDUINO

GND          =     -ve of green , red LED and

                          GND of rain sensor

5V              =     VCC of rain sensor

2                =      +ve of red LED

3                =      +ve of green LED 

4                =      OUT/DC of rain sensor

CODE OF THE PROJECT :-

const int rain= 4;
const int green = 3;
const int red = 2;

void setup() {
pinMode(rain, INPUT);
pinMode(green, OUTPUT);
pinMode(red, OUTPUT);
}

void loop() {
if(digitalRead(rain) == HIGH){
  digitalWrite(green,LOW);
  digitalWrite(red,HIGH);

}

else{
  digitalWrite(green,HIGH);
  digitalWrite(red,LOW);
 
}
}
