Office CO2 Tracker Kit with Arduino Uno + Motor
Monitor Workplace Air Quality: Office CO2 Tracker Kit with Arduino Uno & DC Motor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced Arduino kit puts a full workplace air monitoring and compost aeration system into your hands. Using four DS18B20 temperature probes and a highly accurate MH-Z19B NDIR CO2 sensor, you’ll detect the anaerobic conditions that often build up in poorly vented offices or composting areas. When CO2 spikes or temperature gradients fade, the on-board DC motor kicks in via the L298N driver to mix and aerate the pile, restoring oxygen and keeping the indoor environment safe. It’s a complete sensor-to-actuator pipeline — pre-tested so you focus on the logic, not the troubleshooting.
What You'll Build
A multi-sensor air quality station that reads real-time CO2 (ppm) and four-point temperature data, displays the values on a 0.96-inch OLED, and logs everything to a MicroSD card along with a DS3231 RTC timestamp. The Arduino Uno R3 constantly benchmarks the readings against a set threshold. Once it detects rising CO2 and static temperature — a classic sign of anaerobic stagnation — it sends a signal to the L298N motor driver, rotating a 12V DC fan or stirrer to aerate the compost. The result is an office air quality guardian that acts before anyone notices the stuffiness.
What You'll Learn
- Implement one-wire temperature sensing with multiple DS18B20 probes and resolve address conflicts.
- Interface an NDIR CO2 sensor (MH-Z19B) via UART and interpret PPM data for indoor health standards.
- Log sensor readings with exact timestamps using a DS3231 RTC and a MicroSD module.
- Drive a 12V DC motor through an L298N H-bridge, including direction and speed control.
- Design and solder the full system onto a prototype board, managing power distribution and noise.

Who This Kit Is For
B.Tech ECE and EEE students tackling smart environment projects will find the multi‑sensor fusion exactly what they need for capstone submissions. Smart India Hackathon teams prototyping workplace wellness solutions can hit the ground running with pre‑validated components. The included RTC and SD logging make it ideal for IIT, NIT, VIT, and BITS Pilani students who must present time‑stamped data in their project reports.
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 trained on this exact project—it can walk you through wiring, code debugging, and threshold calibration. If you still need help, our WhatsApp support team responds within a few hours.
Do I need any additional tools?
No extra tools required. The kit includes a soldering iron, solder wire, and a 12V adapter to power the motor, so you have everything to start building immediately.
Can I use this kit for a B.Tech minor or major project?
Absolutely. The DS3231 RTC adds accurate timestamps to your MicroSD logs, making it easy to document environmental changes over time for project reports or hackathon submissions.
How does the compost aeration system work?
The four DS18B20 probes monitor temperature gradients in the compost pile. Combined with the MH-Z19B CO2 sensor, the Arduino detects anaerobic conditions—high CO2 and low temperature variations—and triggers the L298N-driven DC motor to run a small fan or mixer, restoring aerobic decomposition.
Workplace Air — DS18B20 array and CO2 detect anaerobic conditions and trigger relay DC motor to aerate compost.
