Wine Cellar Climate Monitor Pro Kit with Arduino Uno + DHT22
Wine Cellar Climate Monitor Pro Kit — Arduino-Powered PID Control for Perfect Storage Conditions
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
A single-degree fluctuation can ruin years of careful wine ageing. This kit lets you build a full climate monitoring and control station that maintains the ideal 12–14°C and 60–70% humidity your collection demands. Use the waterproof DS18B20 probe to monitor liquid temperature directly inside a representative bottle, while the DHT22 tracks ambient humidity and air temperature. The Arduino Uno runs a PID algorithm to switch a 5V relay — driving a heat mat or small cooler — keeping the cellar within a fraction of your target setpoint.
What You'll Build
You will assemble and program a standalone climate monitor with a crisp OLED readout, microSD data logging with timestamps from the DS3231 real-time clock, and a relay output that regulates an external thermal device. The system logs temperature and humidity every few minutes onto a CSV file you can analyse later for drift patterns, power outage recovery, or seasonal shifts.
What You'll Learn
- Implement a PID control loop in Arduino C++ to stabilise temperature using relay-switched actuators.
- Interface multiple digital sensors (DHT22, DS18B20) on a single I2C and OneWire bus.
- Log timestamped sensor data to a microSD card using the DS3231 RTC for accurate records.
- Design a real-time display dashboard on a 0.96-inch OLED showing current conditions, setpoint, and relay status.

Who This Kit Is For
This kit is built for CBSE Class 11–12 students tackling electronics or computer science projects that demand real-world sensor integration and control theory. B.Tech ECE and EEE undergraduates will find it a tight, well-documented case study in embedded systems, directly applicable to Smart India Hackathon challenges around precision agriculture or cold-chain monitoring. ATL Tinkering Labs can use it to demonstrate closed-loop control, and hobbyists from IIT, NIT, VIT, and BITS campuses working on smart farming prototypes will appreciate the ready-to-assemble components.
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 to open the AI companion; it recognises where you are and offers step-by-step guidance. You can also drop a WhatsApp message with a photo of your board and our support engineers will respond the same day.
Can I replace the heat mat with a cooling fan or Peltier module?
Yes, the relay module can switch any 5V–30V DC load up to 10A. Just ensure your actuator matches the relay rating and adjust the Arduino code's PID direction accordingly.
Does the DS18B20 probe need to be submerged in a bottle of wine?
While submerging the waterproof probe inside a sacrificial bottle or a dummy liquid container accurately reflects wine temperature, you can also attach it to the outside of a bottle with insulating tape for a close approximation.
How do I read the logged data on my computer?
The microSD card stores a CSV file with timestamps, temperature, humidity, and relay state. Remove the card, insert it into your laptop, and open the file with Excel, Google Sheets, or any data analysis tool.
Wine Storage — PID-controlled heat mat holds seedling tray at exact temperature. Humidity logged for germination study.
