HVAC Performance Monitor Kit with Raspberry Pi Zero + DHT22
Capture and Analyze HVAC Performance: Raspberry Pi Zero W Logger with DHT22 and BMP280
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Walk into a room and know exactly how well the air conditioning is performing — minute by minute. This kit turns a Raspberry Pi Zero W into a dedicated HVAC performance monitor that reads temperature, humidity, and barometric pressure from DHT22 and BMP280 sensors, then writes every reading to a CSV file on the SD card. Whether you’re checking if a classroom stays comfortable during summer or validating a B.Tech mini‑project on energy efficiency, you’ll have clean timestamped data ready for spreadsheets or Python analysis.
What You'll Build
A compact environmental data logger that records HVAC performance metrics every 60 seconds. You’ll end up with a continuously growing CSV file containing date, time, temperature, humidity, and atmospheric pressure — perfect for spotting how quickly a room cools down, how humidity changes when the AC cycles on, or whether the pressure stays stable. Everything runs autonomously once you power the Pi Zero W via micro USB.
What You'll Learn
- Interfacing DHT22 and BMP280 sensors with Raspberry Pi GPIO
- Writing a Python script to read sensor data and log it to CSV
- Scheduling repeated measurements with precise timing loops
- Designing a breadboard circuit with pull‑up resistors and decoupling capacitors

Who This Kit Is For
CBSE Class 11–12 students building a data‑logging project for physics or computer science practicals. B.Tech ECE/EEE undergraduates prototyping an environment monitoring module for Smart India Hackathon or mini‑project milestones. ATL Tinkering Lab mentors guiding students toward real‑world IoT applications. If you learn best by building a tool that actually records and visualizes performance, this kit meets you where you are.
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 launch our AI build companion. It knows every step, from soldering the GPIO header to running the Python script. If you prefer, drop us a WhatsApp message — a real engineer will guide you within hours.
Do I need to solder any components?
No soldering required. The kit includes a 40‑pin GPIO header that snaps onto the Pi Zero W, and all sensors and resistors plug directly into the breadboard.
Can I use this to monitor HVAC in a server room or cold storage?
Absolutely. The DHT22 covers 0–100% humidity and -40°C to 80°C, while the BMP280 measures pressure and temperature. As long as the Pi is within Wi‑Fi range of your network (optional) and powered via micro USB, it will log every minute.
Will the 16GB SD card fill up quickly?
Each CSV line is only a few bytes. Even at one entry per minute, 16GB can hold decades of data. The Pi writes directly to the card, so you can safely run it for weeks without worry.
HVAC — Raspberry Pi Zero W reads DHT22 and BMP280. Python script logs to CSV file every minute on SD card.
