ESP32 Humidity Web Server

This project sets up an ESP32 as a Wi-Fi access point that hosts a web server to display real-time humidity data from a DHT11 sensor.

Features

• ESP32 SoftAP Mode: Creates a local Wi-Fi network
• DHT11 Sensor Integration: Reads humidity data
• Web Dashboard: Displays real-time humidity with a progress bar
• JSON API Endpoint: Serves humidity data in JSON format
• Auto Refresh: Updates every 5 seconds

Hardware Requirements

• ESP32 Devkit V1
• DHT11 Humidity Sensor
• Jumper Wires
• Power Source (USB or Battery Pack)

Pin Configuration

Component	ESP32 Pin
DHT11 Data	GPIO 4
VCC	3.3V
GND	GND

Software & Libraries

• Arduino IDE (or PlatformIO)
• ESP32 Board Package
• Libraries:
  • WiFi.h → Enables ESP32's Wi-Fi
  • WebServer.h → Runs the web server
  • DHT.h → Reads sensor data

Installation

1. Clone the Repository:

   git clone https://github.com/shashi4030/HumidityWebServer.git
   cd esp32-humidity-webserver

2. Install Required Libraries:

   • Open Arduino IDE
   • Go to Sketch > Include Library > Manage Libraries
   • Search for and install DHT sensor library and ESP32 WebServer.

3. Upload the Code to ESP32:

   • Connect the ESP32 to your PC via USB
   • Select ESP32 Dev Module as the board
   • Compile and upload the code

Usage

1. Power on the ESP32
2. Connect to the Wi-Fi network: ESP32_Humidity_AP (Password: 12345678)
3. Open a browser and go to 192.168.4.1
4. View real-time humidity updates!

API Endpoints

Endpoint	Description
/	Serves the HTML web page
/humidity	Returns humidity data in JSON

Example JSON response from /humidity:

{ "humidity": 56.7 }
