Pi Zero W GPIO Sensor Logger Kit with Raspberry Pi Zero + DHT22
Raspberry Pi Zero W Sensor Logger Kit: Automatically Log Temperature, Humidity & Pressure to CSV
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a compact, headless data logger that silently records environmental conditions to an SD card every minute — ideal for your school science experiment, a home weather station, or monitoring lab conditions. This kit guides you through assembling a Raspberry Pi Zero W with DHT22 and BMP280 sensors, then running a Python script that timestamps each reading into a CSV file. You'll have complete, analyzable datasets without any cloud dependency or subscription fees.
What You'll Build
You will create a fully functional sensor logger on a breadboard. The Raspberry Pi Zero W reads DHT22 (temperature and humidity) and BMP280 (barometric pressure and temperature) every 60 seconds, appending the data with a timestamp to a CSV file stored on the provided 16GB MicroSD card. The device can run on a USB power bank, making it portable and ready for field deployment. The CSV output is ready for Excel, Google Sheets, or Python pandas analysis.
What You'll Learn
- How to connect I2C and 1-Wire sensors to Raspberry Pi GPIO pins
- Writing Python scripts to interface with DHT22 and BMP280 using standard libraries
- Creating timestamped CSV log files and managing file I/O on Linux
- Practical breadboard assembly and signal conditioning with resistors and capacitors

Who This Kit Is For
This intermediate kit is designed for CBSE Class 11-12 students building physics or computer science investigatory projects, B.Tech ECE/EEE students working on embedded systems mini-projects, and Smart India Hackathon participants prototyping sensor networks. It's also ideal for ATL Tinkering Labs and hobbyists who want a reliable data-logging setup without soldering.
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?
The AI companion walks you through each connection, and you can send a photo via WhatsApp for human backup — typical response within a few hours.
Can I change the logging interval from once a minute?
Yes, the provided Python script is clearly commented; you can edit the sleep duration to any value required for your experiment.
Do I need to solder the GPIO header to the Pi Zero W?
No, the header can be press-fitted securely into the Pi Zero W’s pads without soldering, and the breadboard holds everything firmly.
What happens if the SD card runs out of space during logging?
The script can be modified to rotate files or stop logging; by default, a 16GB card can store months of minute-by-minute CSV data.
Raspberry Pi Zero W reads DHT22 and BMP280. Python script logs to CSV file every minute on SD card.
