Wine Cellar Climate Monitor Kit with Arduino Mega + DHT22
Precision Wine Cellar Climate Monitor Using Arduino Mega, DS18B20 Probes & DHT22
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Wine collectors and sommeliers understand that temperature stratification can silently ruin an entire vintage. This kit equips you to build a professional-grade climate monitor that maps thermal layers across a cellar—deploy six DS18B20 probes at varying depths and two DHT22 sensors at air level to pinpoint hot spots before they compromise aging. Whether you’re prototyping for a vineyard, a restaurant cellar, or a Smart India Hackathon challenge on post‑harvest storage, every component arrives pre‑checked for seamless compatibility.
What You'll Build
Create a self-contained data logger that continuously reads temperature from six waterproof probes and humidity/temperature from two air-suspended DHT22 units. The 0.96‑inch OLED displays real‑time values, while the DS3231 real‑time clock stamps each reading. All data is written to a MicroSD card as a CSV file, enabling long‑term analysis of thermal patterns. You’ll also solder sensors onto a PCB prototype board, package the system in an enclosure, and have a field‑ready monitoring tool that can alert you the moment a 2‑3°C deviation appears between top and bottom barrels.
What You'll Learn
- Implement the 1‑Wire protocol to address up to six DS18B20 sensors on a single bus without conflict
- Use the DS3231 RTC library to generate accurate time‑stamped logs even during power cycles
- Write efficient SD card file management routines that create daily CSV logs and prevent data loss
- Integrate an I2C OLED display to cycle through all eight measurement channels in a clean dashboard view

Who This Kit Is For
Designed for B.Tech students in agriculture or electronics engineering who need a capstone project on smart storage, Smart India Hackathon teams building post‑harvest monitoring solutions, and wine industry professionals prototyping cellar automation. If you’ve ever worked with 1‑Wire sensors or want a hands‑on way to master data logging with Arduino Mega, this kit places exactly the right components in your hands—no hunting through multiple suppliers.
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 launch our AI companion, which recognizes the exact wiring and code for this kit. You can also reach the Compoden team on WhatsApp for human backup within hours.
Can this kit be adapted for grain silos or cold storage monitoring?
Yes, the same multi‑probe approach works for any storage environment. You may need longer probe cables; the kit’s 1‑Wire bus can easily extend with external wiring.
Does this kit include a power supply for continuous operation?
The 9V battery snap is ideal for portable testing. For permanent cellar installation, pair it with a standard 9V DC adapter (not included) connected via the Arduino’s barrel jack.
How accurate are the DS18B20 probes for wine cellar monitoring?
Each DS18B20 is factory‑calibrated to ±0.5°C accuracy in the –10°C to +85°C range, more than adequate to detect the 2–3°C stratification that accelerates wine aging.
Can I export the logged data to my laptop?
Absolutely. The MicroSD card stores daily CSV files with time‑stamped readings. Just pop the card into any computer and open with Excel or Google Sheets to graph temperature trends over weeks.
Wine Storage — Six DS18B20 probes at different depths + DHT22 at air level detect hot spots in stored grain bin.
