A Python AI model to predict and optimize trash collection
A dashboard for real-time updates and alerts
💡 SECTION 1: TECHNOLOGIES AND COMPONENTS
📌 1. ESP8266 (NodeMCU)
What is it?
A small, affordable Wi-Fi microcontroller board used for IoT projects.
Why is it used?
It connects to the internet and sends trash bin data (like bin level) to
your backend server.
📌 2. HC-SR04 Ultrasonic Sensor
What is it?
A sensor that measures distance using sound waves.
Why is it used?
It measures how full the trash bin is by calculating the distance between the
lid and the trash inside.
📌 3. PHP (Hypertext Preprocessor)
What is it?
A server-side scripting language used to build dynamic websites.
Why is it used?
It handles the backend of your system — collecting data, saving to
the database, processing logic, and displaying info on the
dashboard.
📌 4. MySQL
What is it?
A popular open-source relational database system.
Why is it used?
To store data about bins, sensors, users, and AI predictions in organized tables.
📌 5. PDO (PHP Data Objects)
What is it?
A secure and flexible way for PHP to connect and interact with MySQL
databases.
Why is it used?
It allows you to safely insert, update, and fetch data using modern coding
practices.
📌 5. PDO (PHP Data Objects)
What is it?
A secure and flexible way for PHP to
connect and interact with MySQL
databases.
Why is it used?
It allows you to safely insert, update, and
fetch data using modern coding practices.
📌 6. Python
What is it?
A powerful, easy-to-read programming language used for data science,
AI, and automation.
Why is it used?
Python will run your AI models to predict when bins will get full and
calculate optimized collection routes.
📌 7. AI/ML (Artificial Intelligence / Machine Learning)
What is it?
AI is the simulation of human intelligence in machines. ML is a type of AI that learns from data.
Why is it used?
Your system will predict trash bin fill times and suggest efficient routes based on past data.
📌 8. TensorFlow Lite or Scikit-learn
What is it?
Lightweight Python libraries used for running AI models on small devices or simple setups.
Why is it used?
They're perfect for low-budget systems — they allow you to make predictions without needing big servers.
📌 9. HTML, CSS, JavaScript (Frontend Tech)
What are these?
o HTML: Structures the content of your webpage
o CSS: Styles the page (colors, fonts, layout)
o JavaScript: Adds interactivity (dynamic updates, animations)
Why are they used?
To build a clean and user-friendly dashboard to display bin levels, alerts, and AI reports.
📌 10. Bootstrap
What is it?
A free CSS framework for building responsive and mobile-friendly websites.
Why is it used?
It helps you create a professional-looking dashboard quickly without designing everything from scratch.
📌 11. XAMPP or Laragon
What is it?
A local development environment for running PHP, MySQL, and Apache on your computer.
Why is it used?
It allows you to build and test your web system offline before deploying it online.
📌 12. API (Application Programming Interface)
What is it?
A way for two systems (like PHP and Python, or ESP8266 and PHP) to talk to each other.
Why is it used?
APIs let your ESP8266 send sensor data to PHP and allow PHP to get predictions from your Python AI
🧠 SECTION 2: FEATURES AND HOW THEY WORK
🚮 1. Real-Time Bin Monitoring (with IoT Sensors)
What it is: Uses ultrasonic sensors (HC-SR04) connected to ESP8266 to measure how full each bin is.
Why it's used: Helps track bin levels accurately and automatically.
How it works: The sensor measures the distance from the lid to the trash. The data is sent over Wi-Fi to the PHP backend,
where it's stored and visualized.
📊 2. Dashboard Display
What it is: A responsive web interface (PHP/HTML/CSS/Bootstrap) that shows real-time bin data.
Why it's used: Allows the admin to monitor all bins from one place.
How it works: Data from MySQL is fetched using PHP and displayed using HTML/Bootstrap cards and charts.
⏳ 3. AI-Based Trash Level Prediction
What it is: A Python-based AI model that predicts when a bin will be full.
Why it's used: Helps plan collection schedules before bins overflow.
How it works: A simple time-series or linear regression model analyzes past fill rates. PHP sends recent data to the Python
script (via API or shell_exec()), and the script returns the predicted time to full.
🧭 4. Smart Collection Route Optimization
What it is: Determines the most efficient route to collect trash from multiple bins.
Why it's used: Saves fuel, time, and effort for collectors.
How it works: Based on the bin locations (coordinates) and status, a route optimization algorithm (e.g., nearest neighbor)
calculates the best path. The result is shown on a map or list in the dashboard.
🔔 5. Full Bin Notification + QR Code Collector Access ✅ (New Feature!)
💡 What it is:
A smart alert + access system that notifies the admin when a bin is full and uses a QR code to ensure only the assigned collector
can open it.
🎯 Why it's used:
Notifies admins instantly when action is needed
Prevents unauthorized access to bins
Ensures accountability and efficient collection
🛠️
How it works (Step-by-step):
1. Detection: When a bin reaches 90% capacity, the system marks it as Full.
2. Notification: A notification pops up in the admin dashboard (optionally sent via email).
3. Assignment: Admin clicks “Assign Collector” and selects a registered collector.
4. QR Generation: A unique, secure QR code is generated for the assigned collector + bin.
5. Scanning & Verification:
o Collector scans the QR code using a mobile device or app.
o The system checks if the collector is authorized and the QR code is valid.
o If valid, the bin can be opened (optionally connected to a servo motor via ESP8266).
6. Logging: The system records the collection event for tracking and reporting.
🧰 Tools Used:
PHP + MySQL: To manage collectors, bin status, and logs
PHP QR Code Library: To generate QR codes
JavaScript/HTML5: For scanning QR in-browser (optional)
ESP8266: To unlock bin lid (if implemented)
PHPMailer (optional): To send email alerts to admin
📝
Database Tables:
bins: Stores status, assigned collector, and QR data
collectors: List of authorized users who can collect
collection_logs: Records who emptied which bin and when
