Office CO2 Tracker Pro Kit with ESP32 + DHT22
Office CO2 Tracker Pro Kit – Matter‑Enabled Environmental Monitor with ESP32‑C6
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your desk into a health‑aware workspace. This kit transforms an ESP32‑C6 into a compact hub that measures CO₂, temperature, and humidity, then broadcasts those readings as native Matter accessories to Apple Home, Google Home, and other ecosystems. Monitor stale meeting‑room air, optimise ventilation, and see real‑time data on the built‑in OLED – all while learning how industrial‑grade CO₂ sensing and modern smart‑home standards work under the hood.
What You'll Build
You’ll assemble a sleek, wall‑ or desk‑mountable monitor that reads CO₂ concentration from the MH‑Z19B NDIR sensor, temperature and humidity from the DHT22, and displays all three values on a crisp 0.96‑inch OLED. The ESP32‑C6, flashed with our provided firmware, advertises each sensor as an independent Matter accessory. Pair it with your existing Matter controller and automate actions like turning on a fan when CO₂ exceeds 800 ppm – no cloud dependency, no subscription.
What You'll Learn
- Interfacing NDIR CO₂ sensors (MH‑Z19B) via UART for accurate ppm readings
- Reading and calibrating the DHT22 digital temperature/humidity sensor
- Driving a 0.96‑inch OLED display over I²C to show live air‑quality metrics
- Configuring the ESP32‑C6 as a Matter‑compliant sensor accessory step by step
- Designing a stable power stage with an LM2596 buck converter for reliable 3.3V/5V rails

Who This Kit Is For
CBSE Class 11‑12 students exploring practical IoT and smart‑home concepts will find the Matter integration eye‑opening. B.Tech ECE/EEE undergraduates can use the kit as a foundation for air‑quality monitoring projects, Smart India Hackathon prototypes, or environmental sensing coursework. ATL Tinkering Lab mentors will appreciate how the intermediate build bridges the gap between basic Arduino kits and real‑world industrial sensors.
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 start a conversation with our AI companion, trained on every step of this specific project. If you need a human touch, our WhatsApp support responds within hours.
Does this kit support Apple HomeKit or Google Home?
Yes. Once you flash the Matter firmware, the ESP32‑C6 becomes a native Matter device that works with Apple Home, Google Home, and Amazon Alexa without bridges or third‑party apps.
Is soldering experience required?
Basic soldering skills are needed to mount the OLED, resistors and capacitors on the prototype board. The included soldering iron and step‑by‑step AI guidance make this approachable even for beginners.
Do I need a separate Matter hub?
A Matter‑compatible controller (Apple HomePod, Google Nest Hub, or Amazon Echo 4th Gen) is required to add the sensor to your smart home. The OLED display and web dashboard work standalone on your local WiFi.
Workplace Air — ESP32-C6 exposes temperature, humidity and CO2 as Matter sensor accessories. Tiny hub for whole home.
