Industrial Dust Monitor Kit with ESP32 + Sensor
Industrial Dust Monitor Kit with ESP32 – Build a PM2.5, CO2 & AQI Monitor Cube
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn a 50×50×50 mm cube into a factory air sentinel. This ESP32 kit unites particulate, CO2, temperature, humidity, and VOC sensing into one handheld monitor that computes and displays a real‑time AQI index. BLE and WiFi let you stream data to a phone or cloud dashboard — a compact IoT solution for industrial hygiene and hackathon prototypes.
What You'll Build
Assemble a self-contained air quality station that shows a blended AQI score on its OLED. The cube slurps factory air past the PMS5003 laser counter and NDIR CO2 sensor, while BME680 adds environmental context. With dual wireless stacks you can toggle between BLE‑to‑phone and WiFi‑to‑dashboard operation, perfect for on‑site safety audits or a Smart India Hackathon demo.
What You'll Learn
- Orchestrate I2C and UART sensors (BME680, MH‑Z19B, PMS5003) on one ESP32 without bus conflicts
- Compute an AQI score from PM2.5 and CO2 breakpoints and render it on a 0.96‑inch OLED
- Build a BLE GATT server to stream sensor data to a mobile app
- Design a compact, noise‑free power rail with buck conversion, 4.7kΩ pull‑ups and 100nF decoupling caps

Who This Kit Is For
Built for final‑year B.Tech ECE/EEE students at IITs, NITs, VIT or BITS, Smart India Hackathon teams tackling air quality themes, and early‑career industrial safety officers who want to prototype a low‑cost condition monitoring node. The 18‑21 age bracket assumes you are comfortable juggling I2C, UART, and wireless stacks — and ready for a rewarding 5‑hour build that results in a genuine factory‑ready sensor cube.
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?
Scan the QR code for the AI companion that walks you through every wiring and code step, or WhatsApp our Bengaluru team for personalised help.
Can this cube run continuously on a factory floor?
Yes, the LM2596 converter and ventilated enclosure support 24/7 operation; just keep it away from direct water jets.
Are code examples for BLE and WiFi included?
The AI companion supplies ready‑to‑upload Arduino sketches with BLE GATT services and WiFi MQTT publishing logic.
How accurate are the PM2.5 and CO2 sensors?
PMS5003 laser scattering correlates within ±10% of reference monitors. The MH‑Z19B NDIR sensor is accurate for ambient tracking; calibration guidance is included.
Factory Air — 50x50x50mm cube with ESP32, BME680, CO2 and PM2.5 sensor. OLED face shows AQI. BLE and WiFi dual stack.
