Build an Aquaponics Entry Counter with ESP32-S3 WiFi Dashboard Kit

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

Track every entry into your aquaponics room without lifting a finger. This kit turns an ordinary doorway into a live counting system using an invisible infrared beam. When someone or something crosses the beam, the ESP32-S3 increments a counter, updates a crisp OLED display, and pushes the latest value to a browser dashboard over WiFi-giving you real-time monitoring from any device on the same network. Perfect for school labs, home aquaponics setups, or Smart India Hackathon prototypes.

What You'll Build

You'll assemble a complete entry counter that mounts across a door frame. An IR LED emits a beam toward a photodiode; when interrupted, the LM393 comparator sends a clean pulse to the ESP32-S3. The microcontroller displays the count locally and hosts a lightweight web page you can check from a laptop or phone. In under three hours, you'll have a functional IoT monitoring tool ready to deploy in your aquaponics system.

What You'll Learn

• Build a stable IR break-beam sensor circuit using an LED, photodiode, and voltage comparator
• Program an ESP32-S3 to handle GPIO interrupts and maintain a reliable count
• Create a built-in web server that refreshes live sensor data on a browser dashboard
• Integrate an OLED screen for local readout and troubleshoot signal noise with decoupling capacitors

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This beginner-level kit is designed for CBSE Class 11-12 students showcasing agriculture-IoT exhibits, B.Tech ECE/EEE undergraduates prototyping smart monitoring solutions, and teams participating in Smart India Hackathon or ATL Tinkering Lab challenges. It assumes no prior soldering; everything pops onto the included breadboard. If you've ever used an Arduino IDE, you're already overqualified-the AI companion will fill any gaps.

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.
