Arduino DHT Sensor Data to Firebase

This Arduino sketch reads temperature and humidity from a DHT11 sensor and sends the data to Firebase Realtime Database.

Requirements

• Arduino board (e.g., ESP32)
• DHT11 temperature and humidity sensor
• Access to Firebase Realtime Database

Setup Instructions

1. Install Libraries:

   • Make sure you have the following libraries installed in your Arduino IDE:
     • Firebase ESP32 Client
     • DHT Sensor Library

2. Update Wi-Fi Credentials:

   • Replace ssid and password in the sketch with your Wi-Fi network credentials.

3. Firebase Configuration:

   • Replace FIREBASE_HOST with your Firebase Realtime Database URL.
   • Replace FIREBASE_AUTH with your Firebase Legacy Authentication token.

4. Connect DHT Sensor:

   • Connect your DHT11 sensor to the specified digital pin (DHTPIN).

5. Upload and Run:

   • Upload the sketch to your Arduino board and open the Serial Monitor to view temperature, humidity, and Firebase interaction logs.

Firebase Database Structure

• Data is stored under the /DHT11 node in Firebase with the following structure:

  /DHT11
      /Humidity: <value>
      /Temperature: <value>
      /HeatIndexC: <value>
      /HeatIndexF: <value>
  

Troubleshooting

• Sensor Read Failures: If readings fail, check sensor wiring and connections.
• Firebase Errors: Ensure correct Firebase credentials and network connectivity.

Contributing

• Fork the repository, make your changes, and submit a pull request.
• Report issues or suggestions using GitHub issues.

ESP32 Temperature Monitoring with Firebase Integration

This project demonstrates how to monitor temperature and humidity using a DHT11 sensor with an ESP32 board. The sensor readings are sent to Firebase Realtime Database for remote monitoring.

Components Used

• ESP32 Development Board
• DHT11 Temperature and Humidity Sensor
• Firebase Realtime Database

Pin Connections

ESP32 Pinout:

DHT11	ESP32
+	3.3V
OUT	GPIO 4 (D4)
-	GND

Firebase:

Firebase RTDB	ESP32
VCC	3.3V/5V
GND	GND
SCL	GPIO 21 (D21)
SDA	GPIO 22 (D22)

---

markdown Copy code

Notes:

• DHT11: Connect the VCC pin to 3.3V or 5V based on your ESP32 board's voltage, OUT to GPIO 4 (D4), and - to GND.
• Firebase: Ensure correct power supply (VCC and GND) and connect SCL to GPIO 21 (D21) and SDA to GPIO 22 (D22) on ESP32.

Usage

1. Setup Firebase:

   • Create a Firebase project and enable Realtime Database.
   • Note down your Firebase project details (FIREBASE_HOST, FIREBASE_AUTH) and replace them in the Arduino sketch.

2. Upload Code:

   • Upload the provided Arduino sketch (esp32temp.ino) to your ESP32 board using the Arduino IDE.

3. Monitor Data:

   • Open the Serial Monitor to view temperature, humidity, and heat index readings.
   • Check Firebase Realtime Database for remote monitoring of sensor data.
