Pi Zero W Air Quality Badge Kit with Raspberry Pi Zero + Sensor
Build a Wearable Air Quality Monitor: Pi Zero W Air Quality Badge 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.
Create a wearable air quality badge that continuously monitors your environment and displays a real-time air quality score on a crisp OLED screen. Whether you're assessing classroom air, doing a field study, or prototyping a Smart India Hackathon submission, this Pi Zero W kit puts a compact sensor array and display in a battery-powered, portable form factor.
What You'll Build
A fully portable air quality monitor that shows an aggregated air quality index based on volatile organic compounds, CO₂‑equivalent levels, temperature, humidity, and air pressure. The badge clips onto a bag or lanyard, runs from a LiPo battery, and updates readings every few seconds. You'll have a functional prototype ready to take to a science fair or use as a personal exposure tracker.
What You'll Learn
- Interfacing multiple I2C sensors (BME680 and OLED) simultaneously on the Raspberry Pi Zero W
- Reading analog gas sensor values using the MQ-135 and converting to a meaningful air quality index
- Configuring a LiPo battery with TP4056 charging module for portable power
- Writing Python scripts to aggregate sensor data and display a custom air quality score on an OLED

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part | Pre-tested as a system |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Ideal for CBSE Class 11-12 students building a sensor-based project for physics or computer science, B.Tech ECE/EEE undergraduates prototyping for hackathons like Smart India Hackathon, and ATL Tinkering Labs mentoring students on real-time environmental monitoring. Perfect for anyone wanting a wearable electronics project that combines Python, I2C, and power management.
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 inside the box to access the AI companion that has been trained on this exact air quality badge project. It provides step-by-step troubleshooting, and you can reach us on WhatsApp if you need a human look.
Can I modify the air quality algorithm to include other sensors?
Yes, the I2C bus lets you attach additional modules like a particulate sensor later. Our AI companion can guide you through modifying the Python code to incorporate extra data streams.
How long does the battery last when worn?
With the 1000mAh LiPo, continuous sensing and OLED display draw yields about 4–5 hours of runtime. Implementing sleep modes can easily extend it to a full day for intermittent monitoring.
Is this kit suitable for a school science exhibition?
Absolutely. It includes project documentation tailored for CBSE/ICSE exhibition formats, and the wearable badge demonstrates real-world environmental monitoring with clear, visual output.
Pi Zero W reads MQ-135 and BME680 and shows air quality score on tiny OLED. LiPo battery powered.
