Pin Description | পিন পরিচিতি
- VCC – Power supply input
- GND – Ground connection
- DO – Digital output signal
- AO – Analog output signal
The digital output gives HIGH/LOW signal based on the sensitivity setting.
The analog output gives variable signal according to the amount of water detected on the sensor plate.
How It Works | কীভাবে কাজ করে
The raindrop sensor plate has exposed conductive tracks. When water droplets fall on the plate, conductivity changes between the tracks. The control module detects this change and sends an output signal to the microcontroller.
Raindrop sensor plate-এর conductive track-এর উপর পানি পড়লে conductivity পরিবর্তন হয়। Control module সেই পরিবর্তন detect করে Arduino বা ESP32-তে signal পাঠায়।
You can use the signal to turn on a buzzer, close a window, activate a relay, send an IoT alert, or start an automatic rain response system.
Arduino Example Code
#define RAIN_DIGITAL_PIN 2
#define RAIN_ANALOG_PIN A0
void setup() {
Serial.begin(9600);
pinMode(RAIN_DIGITAL_PIN, INPUT);
}
void loop() {
int digitalValue = digitalRead(RAIN_DIGITAL_PIN);
int analogValue = analogRead(RAIN_ANALOG_PIN);
Serial.print("Digital Output: ");
Serial.print(digitalValue);
Serial.print(" | Analog Value: ");
Serial.println(analogValue);
if (digitalValue == LOW) {
Serial.println("Rain Detected!");
} else {
Serial.println("No Rain");
}
delay(1000);
}Important Notes | গুরুত্বপূর্ণ নোট
- The sensor plate is exposed and may corrode over time if kept wet for long periods.
- The control module board is not waterproof.
- Keep the control board protected from rain and moisture.
- Only the sensing plate should be placed where raindrops can fall.
- For outdoor use, place the control circuit inside a waterproof enclosure.
- Clean and dry the sensor plate after long-term use.
- Sensitivity can be adjusted using the onboard potentiometer.
- Product color, PCB marking, and layout may vary depending on stock batch.
