Smart Eco-llection Bin

A smart recycling kiosk that counts and identifies deposited sachets with computer vision, rewards users with points, and syncs every transaction securely to the cloud.

See It in Action

This walkthrough shows a full session on the Smart Ecobin Machine — from scanning a QR ID, through depositing sachets on the conveyor, to receiving a digital receipt and leaving feedback.

Create an engaging user experience for a recycling machine that motivates public participation while handling real-world sensor data and environmental conditions.

How It Works

Every session follows the same simple loop, designed for quick, self-service use in public venues.

  1. Main Page of the Smart Ecobin Machine kiosk
    1Main Page

    Scan to Log In

    The kiosk idles on the welcome screen while it syncs with the server. Users start a session by scanning their RESTORE QR ID, or continue as a guest. Live bin capacity and a "Report Here" shortcut are always visible.

    Open Your Profile

    Once authenticated, the user lands on their dashboard where they can check badges, check their point balance, or start depositing sachets.

  3. Deposit Page of the Smart Ecobin Machine kiosk

    Deposit Sachets & Earn Points

    Selecting Deposit starts the conveyor. Each sachet is captured by the camera, classified on-device by the ML model, and counted in real time — points and sachet totals update instantly on screen.

  4. Transaction Page of the Smart Ecobin Machine kiosk

    Choose Where to Save Points

    After 300 sachets, or whenever the user taps Submit, the session ends and they pick where their points go — such as their Restore Account — before completing the transaction.

  5. Receipt Page of the Smart Ecobin Machine kiosk

    Get a Digital Receipt

    The kiosk sends the encrypted transaction to the web server and generates a digital receipt with a reference number, voucher code, and QR code that the user can photograph as proof.

  6. Feedback Survey of the Smart Ecobin Machine kiosk

    Share Feedback

    Before finishing, a quick emoji-based survey captures how the experience went. The kiosk then resets to the welcome screen, ready for the next user.

Under the Hood

On-Device Item Recognition

Unity Sentis runs a machine learning model directly on the kiosk to identify each deposited sachet in real time.

Hardware Integration

Serial communication via Ardity connects the app to the QR scanner, conveyor belt, scale, and NFC reader, with a main-thread dispatcher bridging serial threads safely.

Secure Transactions

AES-encrypted payloads protect user data and transaction logs, which are synced to the backend through REST APIs.

Friendly Kiosk UX

Large touch targets, emoji icons, Lottie animations, and LeanTween transitions keep the self-service flow clear and engaging.

Solution

Developed a Unity-based application with sensor-driven gamification mechanics. Integrated IoT devices through serial and RESTful protocols, implemented real-time feedback systems, and optimized for public venue deployment with robust error handling.

Results

Successfully deployed in multiple public venues with positive user engagement metrics and increased recycling participation.
