Industrial Bin Level Monitor Pro Kit with ESP32 + DHT22: Build a WiFi Sensor that Serves Inventory Data as JSON

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

Picture a factory floor where a manager can check the fill level of every material bin from a browser on the local WiFi. This kit lets you build that system—an ESP32 microcontroller reads an ultrasonic distance sensor to gauge bin level, a DHT22 for ambient conditions, and LDRs for lid status, then serves all the data as clean JSON through a REST API that any device on the network can query.

What You'll Build

You'll construct a working industrial inventory monitor that mounts on a bin, wirelessly reports fill percentage, temperature, humidity, and light status via HTTP GET endpoints. The ESP32 becomes a self-contained IoT node—no cloud required—that returns sensor readings in JSON format, ready for dashboards, logging, or alerts.

What You'll Learn

• Programming ESP32 to serve multiple sensor data via RESTful JSON APIs
• Wiring and reading ultrasonic distance sensors (HC-SR04) for bin level measurement
• Integrating DHT22 temperature and humidity data into an IoT project
• Using light-dependent resistors (LDRs) for binary state detection (lid open/closed)

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11–12 students working on computer science or electronics projects that require IoT and API integration. B.Tech ECE/EEE students building mini projects or participating in Smart India Hackathon will find the ready-to-code REST API framework a massive head start. ATL Tinkering Lab mentors can use it as a structured intermediate challenge that moves beyond blinking LEDs into real industrial automation concepts.

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.
