Smart Mess Management System – IoT Based Mess Management System

A complete IoT project for real-time monitoring and management of a mess (dining hall) using ESP32, sensors, and a Python Flask dashboard.

Features

• Occupancy Tracking: Counts people entering and exiting using PIR sensors.
• Environmental Monitoring: Measures temperature and humidity using a DHT22 sensor.
• Waste Bin Monitoring: Detects bin fill level with an ultrasonic sensor and alerts when full.
• Live Dashboard: Real-time data visualization and historical data via a Flask web app.
• RESTful API: ESP32 sends data to the server using HTTP POST in JSON format.
• User Authentication: Login system for accessing and saving historical records.
• Cross-Platform: Designed for deployment on Linux (tested in VMware and Raspberry Pi OS).

Technologies Used

• ESP32 (Arduino IDE, C++)
• Sensors: PIR, DHT22, Ultrasonic (HC-SR04)
• Python 3, Flask, SQLite
• HTML, CSS, JavaScript
• Wi-Fi, HTTP/REST

How It Works

1. ESP32 collects sensor data and sends it via Wi-Fi to the Flask server.
2. The Flask server stores and displays the data on a web dashboard.
3. Users can view live mess stats, historical data, and receive alerts for full bins.
