ESP8266 Weather Monitoring Dashboard

Overview

This project uses an ESP8266 microcontroller with BMP085 and DHT11 sensors to monitor temperature, humidity, pressure, and altitude. The sensor readings are displayed in real-time on a web dashboard accessible from a browser.

Components Used

• ESP8266 NodeMCU
• BMP085 Pressure Sensor
• DHT11 Temperature and Humidity Sensor
• LEDs and resistors (for indication)
• WiFi Router

Libraries Required

• ESP8266WiFi
• WiFiClient
• ESP8266WebServer
• Wire (for I2C communication)
• Adafruit_BMP085 (for BMP085 sensor)
• DHT (for DHT11 sensor)

Installation and Setup

1. Hardware Setup:

   • Connect the BMP085 sensor and DHT11 sensor to the ESP8266 according to the wiring specified in your code (DHTpin, A0, I2C pins for BMP085).

2. Software Setup:

   • Install the Arduino IDE and necessary libraries (ESP8266WiFi, Adafruit_BMP085, DHT).
   • Copy the provided code into the Arduino IDE.
   • Modify the code to include your WiFi SSID and password (ssid and password variables).

3. Upload the Code:

   • Select the appropriate board and COM port in the Arduino IDE.
   • Click on Upload to upload the code to your ESP8266.

4. Accessing the Dashboard:

   • Once uploaded, open the Serial Monitor to view the ESP8266's IP address.
   • Enter this IP address in a web browser on your local network to access the real-time weather dashboard.

Usage

1. Web Dashboard:

   • The dashboard displays charts (using Chart.js) for altitude, temperature, and humidity.
   • Data is updated dynamically using AJAX requests to the ESP8266 server (readADC endpoint).

2. LED Indication:

   • The onboard LED (LED pin) toggles with each data update, indicating server activity.

Notes

• Ensure stable WiFi connectivity for reliable data updates.
• Customize the HTML (index.h) and JavaScript (<script> section in index.h) for additional features or visual enhancements.
