Interfacing Rain Sensor with Raspberry Pi 3 ☔

Interfacing Rain Sensor with Raspberry Pi 3 ☔

🎯 Objective

To detect the presence of rain using a Rain Sensor module with Raspberry Pi 3 and display alerts on the console. Perfect for smart weather stations and automatic window systems!

🧰 Components Required

ComponentQuantity
Raspberry Pi 31
Rain Sensor Module (Analog & Digital Output)1
Jumper WiresAs required
Breadboard1

⚡ Circuit Connections

Rain Sensor PinConnect To
VCC5V (Raspberry Pi)
GNDGND (Raspberry Pi)
D0 (Digital Out)GPIO17 (Pin 11)

🧠 Python Code

import RPi.GPIO as GPIO
import time

RAIN_SENSOR_PIN = 17

GPIO.setmode(GPIO.BCM)
GPIO.setup(RAIN_SENSOR_PIN, GPIO.IN)

try:
    while True:
        if GPIO.input(RAIN_SENSOR_PIN) == 0:
            print("🌧️ Rain Detected!")
        else:
            print("☀️ No Rain.")
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()

📊 Output

  • Prints "🌧️ Rain Detected!" when water droplets are sensed.
  • Otherwise prints "☀️ No Rain."

💡 Applications

  • Smart weather monitoring
  • Automatic rain-sensing wipers/windows
  • Rain alert systems for farmers

🎯 उद्दिष्ट

रेन सेन्सर वापरून पावसाची उपस्थिती शोधणे आणि रास्पबेरी पाय 3 वर कन्सोलमध्ये अलर्ट दर्शविणे.

🧰 लागणारे साहित्य

🧠 पाइथन कोड

import RPi.GPIO as GPIO
import time

RAIN_SENSOR_PIN = 17

GPIO.setmode(GPIO.BCM)
GPIO.setup(RAIN_SENSOR_PIN, GPIO.IN)

try:
    while True:
        if GPIO.input(RAIN_SENSOR_PIN) == 0:
            print("🌧️ पाऊस सुरू आहे!")
        else:
            print("☀️ पाऊस नाही.")
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()

📊 आउटपुट

  • पाणी आल्यावर "🌧️ पाऊस सुरू आहे!" असे प्रिंट होते.
  • नसल्यास "☀️ पाऊस नाही." असे प्रिंट होते.

💡 उपयोग

  • स्मार्ट हवामान यंत्रणा
  • स्वयंचलित विंडो/वायपर सिस्टम्स
  • शेतीसाठी पावसाचे अलर्ट सिस्टीम
