Wine Cellar Climate Monitor Kit with ESP32 + Relay
Wine Cellar Climate Monitor Kit with ESP32 & MQTT Relay Control – Preserve Your Collection Remotely
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 self-regulating environment that maintains perfect temperature and humidity, and alerts you instantly if conditions drift. This ESP32-powered monitor lets you control cooling, lighting, and access remotely via any MQTT client on your phone or laptop.
What You'll Build
You’ll assemble a wireless climate monitor that continuously reads temperature and humidity using a precision DHT22 sensor, displays data on an OLED screen, and triggers relays to control a fan, air conditioner, light, and an electromagnetic lock. Thanks to MQTT, you can monitor and override controls from anywhere—perfect for wine cellars where steady climate is critical.
What You'll Learn
- Program an ESP32 to connect to Wi-Fi and publish/subscribe to MQTT topics
- Interface a DHT22 sensor and 0.96-inch OLED display via I2C
- Use a 4-channel relay module to switch AC and DC loads safely with flyback diodes
- Design an IoT dashboard on a free MQTT client app for remote climate control

Who This Kit Is For
This kit is ideal for CBSE Class 11–12 students building IoT projects for science exhibitions, B.Tech ECE and EEE students prototyping for Smart India Hackathon or capstone projects, and home automation enthusiasts at IIT, NIT, VIT, and BITS Pilani who want to maintain a wine collection or similar climate-sensitive storage.
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 launch the AI companion, which walks you through each step with troubleshooting hints. You can also ping us on WhatsApp for direct guidance.
Can I control more than four appliances?
Yes, each relay channel operates independently. For additional loads, you can cascade a second Compoden relay module using the ESP32’s spare GPIOs.
Does the kit include the fan, light, or lock?
No, the kit provides only the electronic control components. You supply your own appliances rated within the relay’s capacity (10A per channel) tailored to your cellar.
Will this work with an existing wine cellar cooling unit?
Absolutely. The relay can interface with standard cooling systems if power ratings match; the MQTT interface lets you set thresholds for automatic operation.
Wine Storage — ESP32 MQTT controls lights, fan, AC relay and lock from any MQTT client app.
