How to use The Raindrops Detetion Sensor Module

The raindrops detection sensor module is a sensor that detects water drops with a voltage limit from 3.3V-5V. In this guide, we will be using the Raindrops Detection Sensor Module from our store.

Part

• Raindrops Detection Sensor Module
• M/M Jumper wires
• Arduino Uno R3
• Arduino IDE

Wiring Guide

Step 1: First of all, connect the sensor module to the sensor

Step 2: Connect the sensor pins with the Arduino

Sensor	Arduino
VCC	5V
GND	GND
A0	A0

Programming

Step 1: Define your pins and values

#define rainfall A0
int value;
int set = 10; //set value to compare to value

Step 2: Start the serial monitor and activate the pin

void setup(){
  Serial.begin(9600);
  pinMode(rainfall,INPUT);
}

Step 3: In loop(), read the value of the sensor and map it out for a new value to compare to set

value = analogRead(rainfall);
value = map(value,0,1023,225,0);

Step 4: Add a if/else statement to tell what the serial monitor should print when water is detected

if(value >= set){
  Serial.println("rain detected");
}else{
  Serial.println("no rain detected");
}
delay(200);

Full Code

#define rainfall A0
int value;
int set = 10;

void setup(){
  Serial.begin(9600);
  pinMode(rainfall,INPUT);
}

void loop(){
 value = analogRead(rainfall);
 value = map(value,0,1023,225,0);
 
 if(value >= set){
  Serial.println("rain detected");
 }else{
  Serial.println("no rain detected");
 }
 
 delay(200);
}
