# Lux Meter with LDR
## Overview
Lux Meter with LDR is an IoT project designed to measure the intensity of light using a Light Dependent Resistor (LDR) and an Arduino UNO. The collected data is then sent to an ESP32 microcontroller, which processes the information and hosts a web server to display the readings in real-time through a user-friendly web interface.

## Features
- Measures light intensity and converts it to lux.
- Displays real-time lux values on a web interface.
- Uses Arduino UNO and ESP32 for data processing and transmission.
- Provides a simple HTTP server to fetch data via GET requests.
- User-friendly web interface with automatic updates.
## Hardware Requirements
- Arduino UNO
- ESP32
- LDR Sensor
- Connecting wires
- Breadboard (optional)
## Software Requirements
- Arduino IDE
- Micropython for ESP32
- VS Code
- Jupyter Notebook
- Python
- Browser
## Installation
### Arduino Setup
1. **Connect the LDR to Arduino UNO**:
- Connect one end of the LDR to the `A0` pin.
- Connect the other end to `5V` through a resistor (10kΩ).
- Connect the junction of LDR and resistor to `GND`.
2. **Upload the Arduino Code**:
- Upload the `LuxMeter.ino` code provided in the Arduino folder.
### ESP32 Setup
1. **Connect ESP32 to WiFi**:
- Modify the `boot.py` script to include your WiFi credentials.
- If needed, set a static IP address in the `boot.py` script.
- Upload the `boot.py` and `main.py` files provided in the ESP32 folder.
2. **Set Up the Web Server**:
- Upload the `index.html`, `script.js`, and `styles.css` files provided in the Web folder to a web server.
## Working
The LDR is setup alog with a 10kΩ resistor in a voltage divider circuit. The corresponding voltages are marked with relevant LUX Values with a `SAMSUNG J7 Pro Light Sensor`. The Experiment is carriedon a few timesand the values are tabulated and furthur put into experiment as elaborated in `equation.ipynb`. These values are then put into `UNO` and the correspondingLUX values against the LDR Voltages are calulated.
These two values are sent over to the ESP32 via UART. The ESP32 then starts a local server at `192.168.1.45` where these two values are packed into a `JSON` and sent over `WiFi`. These two values are then retrieved by a corresponding webpage and displayed with customized CSS.
## Usage
1. **Power Up**: Connect both Arduino UNO and ESP32 to power sources.
2. **Access Web Interface**: Open a web browser and navigate to the IP address of the ESP32 web server.
3. **Monitor Light Intensity**: The web page will display real-time LDR voltage and lux values.
