Lab Gas Monitor Kit v3
Automated Multi-Gas Emissions Monitor for Factory Compliance – Lab Gas Monitor Kit v3 (Raspberry Pi 5)
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Assemble a multi-gas detection array that continuously monitors carbon monoxide, volatile organic compounds, combustible gases, and carbon dioxide levels in a factory environment, comparing readings against regulatory limits and automatically generating compliance reports. Powered by a Raspberry Pi 5 and backed by an AI build companion trained on this exact project, you’ll create a real-world industrial safety prototype that logs data to high‑speed NVMe SSD and serves reports from its own edge server.
What You'll Build
You’ll deploy a real-time gas monitoring station that reads four MQ-series sensors through an ADS1115 16‑bit ADC, logs time‑stamped data, and triggers alerts or compiles a PDF report when emission thresholds approach. The system mimics the setup of small factory and lab safety installations, and can be tuned to match India’s CPCB emission standards. Once built, you’ll have a fully functional edge IoT device that demonstrates sensor fusion, persistent storage, and automated compliance documentation – ideal for showcasing in hackathons or science exhibitions.
What You'll Learn
- Interface multiple analog gas sensors with Raspberry Pi 5 using an ADS1115 ADC and I²C communication
- Calibrate MQ-7, MQ-135, MQ-2, and MQ-9 sensors for accurate concentration readings and cross‑sensitivity compensation
- Design a multi‑threaded Python data logger that writes sensor readings to a 128GB NVMe SSD without blocking the dashboard
- Generate automated compliance reports in PDF/CSV format based on configurable regulatory limits
- Set up a lightweight web dashboard for local or remote monitoring of real‑time emissions

Who This Kit Is For
This intermediate project is crafted for CBSE Class 11-12 science students aiming for a standout exhibition piece, B.Tech ECE/EEE undergraduates preparing Smart India Hackathon submissions with industrial IoT focus, and ATL Tinkering Lab innovators exploring real-world environmental monitoring. If you’re at IIT, NIT, VIT, or BITS, this kit builds your sensor fusion and edge computing skills for industry‑relevant applications in lab safety and emissions compliance.
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 kit includes a QR code that unlocks our AI guide with step‑by‑step instructions specific to your sensors and Pi 5. You can also message us on WhatsApp for a quick human assist — most students complete the full build within 5 hours.
Do the sensors need individual calibration for different gases?
Yes, each MQ sensor requires a baseline calibration. The AI companion walks you through a simple routine using fresh air and, if available, a small calibration gas ampoule. The ADS1115’s 16‑bit resolution ensures stable readings for accurate calibration curves.
Can I view compliance reports from a web browser on another device?
Absolutely. The included software runs a Flask web dashboard on the Pi 5 that serves real‑time sensor values and downloadable reports. We also show you how to set up port forwarding or use a service like ngrok so you can access it from anywhere.
What kind of factory or lab environment can this kit simulate?
The sensor array monitors CO, VOCs, combustible gases, and carbon dioxide — making it suitable for small chemical labs, pharmaceutical storage, and engineering workshops. It’s a prototype for regulatory monitoring, not a certified device, but the data logging and alert logic closely follow real‑world compliance systems.
