Blind Stick Obstacle Detector Kit v4 — Smart Bin Fill Monitoring & Route Optimizer Built Around Raspberry Pi 5

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine six waste bins in a public space, each fitted with an ultrasonic sensor that whispers its fill level to a central brain. That brain — a Raspberry Pi 5 — learns the best possible path to empty them and shows you the route on a dashboard. This kit turns that idea into a functional prototype, equipping you with the same stack used in smart city waste management pilots. Whether you’re refining an ATL Tinkering Lab entry or preparing a Smart India Hackathon demo, you’ll build something that merges accessibility with real-time AI.

What You'll Build

You will assemble a distributed sensor network where two ESP32 dev boards read six HC-SR04 ultrasonic sensors placed inside bins. The ESP32s stream fill-level data wirelessly to a Raspberry Pi 5, which stores the readings on a 128GB NVMe SSD. A machine learning model running on the Pi calculates the shortest collection route visiting only bins that need attention, cutting unnecessary travel. The output is a live route map you can follow on a mobile-friendly web interface.

What You'll Learn

• Wireless sensor networking — connecting multiple ESP32 boards to a Pi 5 over Wi-Fi
• Ultrasonic depth sensing and calibration for consistent fill-level accuracy
• Deploying a lightweight ML model on Raspberry Pi 5 for combinatorial optimization (route planning)
• Visualising real-time sensor data and optimised routes on a web dashboard

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Engineers-in-the-making who want a practical IoT+ML project that solves a real urban problem. If you are a B.Tech ECE or CSE student building a final-year prototype, a CBSE Class 12 innovator working on an ATL accessibility submission, or a team preparing for a hackathon, this kit gives you everything wired and ready. The route optimizer uses the same principles found in logistics systems used by municipalities, so your demo will stand out in any review.
