Wine Cellar Climate Monitor Kit with ESP32 + DHT22 v4
ESP32 Wine Cellar Climate Monitor Kit — 6-Month Data Logging with Live Web Graphs
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 kit turns an ESP32 into a vigilant cellar keeper. It reads temperature, humidity, barometric pressure, and ambient light every 5 minutes, writes time-stamped CSV records to a microSD card, and serves interactive charts on your local WiFi. Whether you are aging a small collection or running a school science project, you get a data-rich instrument that runs for months without a cloud login.
What You'll Build
You'll assemble a standalone climate logger powered by a compact breadboard. The SD card holds over half a year of data, while the built-in web server lets you check trends from any phone or laptop. No app required — just open the ESP32's IP address and see temperature/humidity/pressure/light graphs that update live as new readings arrive.
What You'll Learn
- Precision sensor interfacing: DHT22, BMP280, and two LDRs on the ESP32
- I2C and SPI communication protocols for real-time clock and SD card
- Timestamped data logging with the DS3231 RTC
- Creating an asynchronous web server to serve dynamic SVG charts

Who This Kit Is For
It fits beautifully into CBSE Class 11-12 physics and computer science investigatory projects, especially data logging and IoT experiments. B.Tech ECE/EEE students tackling mini-projects will find a ready-to-expand sensor suite. ATL Tinkering Lab mentors and Smart India Hackathon participants can rely on this kit for robust environmental monitoring without spending weeks on parts procurement.
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?
Open the AI companion from the QR code and describe your issue — it will walk you through wiring, code, or sensor calibration. You can also reach us on WhatsApp for direct help.
Can I view the web graphs from outside my home network?
By default, the web dashboard runs on your local WiFi. To access it remotely, you can set up port forwarding on your router or use a temporary service like ngrok — a great next-level extension.
How reliable is the DHT22 sensor for accurate wine storage conditions?
The DHT22 offers ±0.5°C accuracy, perfectly suited for monitoring wine cellars where temperature should not fluctuate by more than 1–2°C. The AI companion can guide you through a simple calibration offset if needed.
Will this kit work for a larger commercial wine storage facility?
This kit monitors a single point. For larger facilities, you can deploy multiple kits or extend the design with additional sensors over I2C, a natural progression this project prepares you for.
Wine Storage — DHT22 + BMP280 + LDR sampled every 5 minutes. SD card stores 6 months of data. Web graph served over WiFi.
