Smart Recycling Bin Kit

This kit serves one of our pillars: Waste & Circular — technology in the service of nature.

Build a bin that knows when it is full and opens by itself. An ultrasonic sensor measures the level of rubbish inside, the ESP32 sends a WiFi alert when it is time to empty it, and a servo lifts the lid hands-free. The smart side of keeping a city clean.

What's inside the kit?

• ESP-32S 30Pin Dev Board WiFi Bluetooth CP2102 — WiFi brain + alerts
• Ultrasonic Sensor HC-SR04 — Measures how full the bin is
• SG90 Micro Servo Motor 180° 1.8 kg.cm Plastic Gears — Lifts the lid automatically
• 0.96" OLED LCD Module — Shows the fill level
• BB-01 Breadboard 830 Tie Point — Build base
• BB-J140 Connecting Jumper Wires for Breadboard (140 Wire) — Connections

How the idea works

Every part in the kit has a job. Assembled in the right order they stop being loose parts and become a working system — one you build yourself, understand at every step, and see the result of with your own eyes. The included build guide walks you from zero to running.

Your journey: from kit to competition

• Build — assemble the kit and get it running.
• Understand — learn why each part is there and how it works.
• Improve — modify it, add a sensor, tune it, try your own idea.
• Make a project — turn the experiment into a project that solves a real environmental problem.
• Compete — enter your project into local and international competitions.

A good fit for tracks such as:

• Waste & Circular / التدوير

What you'll learn

• How an ultrasonic sensor measures distance and level
• Sending alerts over WiFi (Internet of Things)
• Controlling a servo to automate a mechanism
• How smart bins make waste collection efficient

Extend & innovate

Add a second sensor to separate recyclables, log fill-levels to a city dashboard, and trigger the lid with motion so it is fully touch-free. Scale it into a smart-city waste project.
