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.

If you like this project subscribe us on Youtube, So without wasting time Let's get started..............

Step 1: MATERIAL REQUIRED

To make this project we need some components (Best Buy Link Provided):-

Potentiometer (10K) X 1

Transistor (BC547) X 1

PCB etching kit X 1

Soldering kit X 1

Connection Wires X 1Nos

Rain Drop DIY PCB

Step 2: CIRCUIT DIAGRAM

Follow the circuit diagram to make connections.

Step 3: DIY RAIN DROP SENSOR

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

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

Step 4: ARDUINO CODE

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);
}
 }
