Industrial Bin Level Monitor Kit with ESP32 + Ultrasonic
Industrial Bin Level Monitor Kit with ESP32-S3: Build a Four-Slot Occupancy Dashboard
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 a warehouse where four bins are being filled and emptied. This kit lets you build a monitoring system that checks the level in each bin using ultrasonic sensors and displays real-time occupancy on any device's browser. Whether for a school project or a mini industrial prototype, you'll create a live IoT dashboard that tracks slot states—empty or occupied—over WiFi.
What You'll Build
A fully functional bin-level monitoring station with four ultrasonic sensors mounted on a prototype board. The ESP32-S3 reads distances, determines if each bin is above or below a threshold, and serves an occupancy map as a webpage. You'll also integrate a WS2812B LED strip that lights up to indicate which bays are full, making it a visual alert system.
What You'll Learn
- Calibrating HC-SR04 ultrasonic sensors for reliable distance measurement in cm
- Programming ESP32-S3 to handle multiple sensor inputs and apply slot-state logic
- Creating a real-time WiFi dashboard using HTTP server and ESPAsyncWebServer to display occupancy status
- Soldering components onto a prototyping board to build a permanent, durable circuit

Who This Kit Is For
This kit is perfect for CBSE Class 11-12 students exploring embedded systems, B.Tech ECE/EEE students preparing mini-projects, and teams participating in Smart India Hackathon building industrial IoT solutions. It's also ideal for ATL Tinkering Lab mentors and hostel makers at IIT, NIT, or BITS who need a plug-and-play kit for a quick prototype.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI build companion provides step-by-step guidance, and if you hit a roadblock, WhatsApp support from our team is included. Just scan the QR code to connect.
Is soldering experience required to complete this kit?
The kit includes a soldering iron and solder wire, and the AI companion walks you through each joint with clear visuals. Even first-time solderers can follow along confidently.
Can I monitor the bins remotely over the internet?
The ESP32-S3 creates a local WiFi network that any device can join to view the dashboard. Remote internet access is possible through port forwarding or services like ngrok, though those steps are not included in the build guide.
How accurate are the ultrasonic sensors for bin level detection?
HC-SR04 sensors provide distance readings with approximately 3mm accuracy, sufficient for empty vs. occupied detection. The sample code includes digital filtering to ignore spurious readings and ensure reliable occupancy mapping.
Industrial Inventory — Four HC-SR04 sensors on parking bays. ESP32-S3 runs slot-state logic and publishes occupancy map via WiFi dashboard.
