Monitor Your Wine Cellar's Climate with Arduino Uno & DHT22 Dew Point Sensor

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform your wine storage into a precision-monitored environment with a custom-built climate monitor. This kit uses the accurate DHT22 sensor to track temperature and humidity, then computes the critical dew point — the temperature at which condensation forms — using the Magnus formula. Perfect for wine collectors, home connoisseurs, or STEM learners exploring practical IoT, this project displays real-time readings on a bright OLED screen.

What You'll Build

A compact, battery-powered monitor that continuously displays temperature, relative humidity, and dew point on a crisp 0.96-inch OLED screen. You'll assemble the circuit, upload the pre-tested code, and calibrate the sensor to alert you when your cellar conditions stray from ideal wine preservation ranges. The monitor runs on a 9V battery, making it easy to place inside your wine fridge or rack.

What You'll Learn

• Reading digital sensor data using the DHT22 library on Arduino
• Driving an I2C OLED display to show real-time environmental data
• Implementing the Magnus dew point formula in Arduino C++ to prevent moisture damage
• Structuring sensor projects with breadboard prototyping and power management

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This beginner-friendly kit is ideal for CBSE Class 11-12 students exploring sensor-based projects, B.Tech ECE/EEE freshers prototyping environmental monitors, and ATL Tinkering Lab innovators. Wine enthusiasts and home automation hobbyists will also appreciate building a practical tool for cellar management. Younger makers (5-10) can assemble with parental guidance, while teens can complete it independently in under two hours.

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.
