BME680 Environmental VOC Sensor Kit Kit with Arduino Uno + Sensor
BME680 Environmental VOC Sensor Kit with Arduino Uno: Build an IAQ Data Logger
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Air quality monitoring demands precision, and the BME680 delivers temperature, humidity, barometric pressure, and volatile organic compound (VOC) gas readings. This kit guides you through computing Bosch’s Indoor Air Quality (IAQ) score directly on an Arduino Uno and automatically logging every data point to an SD card with real-time timestamps. From Smart India Hackathon prototypes to final-year B.Tech projects, you’ll create a portable sensor station that turns raw environmental data into actionable insight.
What You'll Build
A stand-alone IAQ monitor that displays real-time temperature, humidity, pressure, and IAQ score on a 0.96-inch OLED. Every reading—including the computed VOC gas index—is stamped by the DS3231 RTC and saved to a microSD card for later analysis. The entire circuit is soldered onto a prototyping board and powered by a 9V battery, giving you a durable, field-ready logger you can carry anywhere.
What You'll Learn
- How to manage multiple I2C devices (BME680, OLED, RTC) on the same bus using address configuration.
- Calculating VOC gas index and implementing Bosch’s proprietary IAQ score algorithm from raw sensor data.
- Building a real-time data logging system with an SPI microSD module and DS3231 time stamps.
- Soldering through-hole components on a prototyping board to create a permanent, reliable environmental monitor.

Who This Kit Is For
Designed for advanced hobbyists and engineering students, especially B.Tech ECE/EEE candidates working on environmental monitoring or IoT assignments. It suits Smart India Hackathon teams building smart city air quality nodes, ATL Tinkering Lab mentors guiding sensor-based projects, and final-year students needing a reliable IAQ data logger for their capstone submission. Basic soldering experience and familiarity with the Arduino IDE are assumed.
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?

How is the IAQ score calculated from the BME680?
We provide Arduino code that reads raw VOC resistance, temperature, and humidity, then applies Bosch’s proprietary library function to output an IAQ index (0–500). This score represents air quality from good (0–50) to hazardous (351–500).
Can I log data continuously for an entire day or longer?
Yes—the DS3231 RTC timestamps every reading, and the microSD module stores data in CSV format. With a fresh 9V battery and a high-capacity SD card, continuous logging for 12–24 hours is typical; external USB power extends operation indefinitely.
Do I need any extra tools besides what’s in the kit?
The kit includes a soldering iron and solder wire, so you have everything to assemble the board. You’ll need a USB cable (standard Arduino Uno cable) and a computer with the Arduino IDE to upload the code—both are not included but are common gear for any maker.
BME680 measures temperature, humidity, pressure and VOC gas index. IAQ score computed and logged to SD.
