Rain Detector Alarm Using Arduino Uno

Hello friends welcome back to "TECHNO-E-SOLUTION", In this article I'll show you "How To Make A Rain Detector Alarm Using Arduino Uno". In this project we need to make a custom Rain drop sensor to detect the rain, so I make a custom rain drop sensor plate. I provide the image of custom rain drop sensor. Make it same. After Summer season Rainy season starts and we need this Rain Detector for our rain alarm purpose in our home, office etc... Hence we are going to make Rain Detector Using Arduino Uno.

Follow the following steps to make PCB using "Tonner transfer Technic"

1. Cut PCB as per your choice.
2. Draw using marker as shown in above image.
3. take a 2-3 spoon of ferric chloride in water.
4. Place PCB in the solution for 5-10 min.
5. Clean the PCB with the help of PCB Cleaner.
6. Drill the PCB using drill machine.
7. Now your PCB Completed.

Make a circuit & Upload following code to Arduino Uno.

Hello Friends Welcome to Techno-E-Solution
Here is the Code For Rain Detector Using Arduino

*/

int RainSensor = 0;
int buzzer = 10;
int LED = 8;
void setup() 
{
  
Serial.begin(9600);
pinMode(buzzer,OUTPUT);
pinMode(LED,OUTPUT);
}
 
void loop(){

int SensorValue = analogRead(RainSensor);

if(SensorValue >=100)

{
   
digitalWrite(buzzer,HIGH);
digitalWrite(LED,HIGH);
Serial.println("RAINING");
delay(1000); 
}
 
else

{ 
digitalWrite(buzzer,LOW);
digitalWrite(LED,LOW);
Serial.println("NOT RAINING"); 
delay(1000);
}
 }
