Meeting Room Ventilation Monitor Kit
Meeting Room Ventilation Monitor: Deploy a Full-Stack IoT Dashboard with MQTT and Grafana
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Most meeting rooms lack real-time ventilation data, leading to drowsy afternoons and reduced productivity. With this kit, you’ll assemble a sensor array that tracks CO2, temperature, and humidity, streams the data over MQTT, and displays it on a Grafana dashboard—all running on a single Linux board. It’s a professional-grade indoor air quality monitor that doubles as a learning platform for full-stack IoT.
What You'll Build
A desktop ventilation monitor that immediately shows when CO2 rises above safe limits. Two DHT22 sensors and one BMP280 capture micro-climate differences across the room, while the MH-Z19B measures carbon dioxide. Data flows from the Arduino to a Mosquitto broker inside a Docker container, and Grafana plots live graphs. The unit sits in an enclosure, powered by a 5V 3A supply, and you access the dashboard from any device on the same network.
What You'll Learn
- Integrate DHT22, BMP280, and MH-Z19B sensors with an STM32-compatible Arduino
- Set up Mosquitto MQTT broker and Grafana using Docker on Linux
- Program MQTT publish/subscribe for real-time sensor data transport
- Prototype PCB sensor nodes and solder an enclosure-ready assembly

Who This Kit Is For
B.Tech ECE and EEE students working on IoT or smart building projects, participants in Smart India Hackathon, and corporate trainees prototyping office ventilation solutions. The kit also fits CBSE Class 12 investigatory projects, ATL Tinkering Lab mentors, and IIT/NIT research groups who need a ready-to-deploy Full-Stack sensor network example.
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 on the box to chat with our AI companion. It’s trained on every step of this project, and you can also reach us on WhatsApp for human help.
Do I need a separate Linux computer for the dashboard?
Yes, the dashboard runs Mosquitto and Grafana inside Docker. You can use any Raspberry Pi, old laptop, or cloud VM with Docker installed. The kit provides the sensor hardware and Arduino code.
Can I use this to monitor multiple meeting rooms?
Absolutely. By duplicating the sensor node and changing the MQTT topic, you can monitor several rooms from one Grafana instance. The kit includes extra resistors and capacitors to support additional prototypes.
Is soldering necessary for this build?
Yes, you’ll solder sensors, resistors, and headers onto the PCB prototype board. The kit includes a soldering iron and solder wire, making it ready to start immediately.
Meeting Room — Docker on Linux runs Mosquitto MQTT + Grafana. STM32 sketch publishes sensor data. Full stack on one board.
