Wine Cellar Climate Monitor Kit v4
ESP32 Wine Cellar Climate Monitor Kit: Mobile GPS & IR Thermometer Heat Map Logger
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Walk through any Indian city with this portable ESP32 logger, capturing surface temperatures via the MLX90614 IR sensor while the NEO-6M GPS stamps each reading with latitude and longitude. Back home, you’ll transform a microSD card of timestamped humidity, ambient, and IR data into a heat map that reveals thermal microclimates — crucial for wine cellar siting, storage insulation validation, or urban heat island analysis. No cloud connection needed; all logging runs offline on the device.
What You'll Build
A battery-powered handheld instrument that logs DHT22 ambient conditions and MLX90614 surface temperatures every second, geotagging each record with GPS coordinates and a DS3231 real-time clock timestamp. The final output is a CSV dataset ready for visualisation, enabling you to map temperature gradients across neighbourhoods, vineyards, or storage facilities and make data-driven decisions about wine storage environments.
What You'll Learn
- Multi-protocol sensor integration on ESP32: I2C for the OLED and MLX90614, UART for GPS, and SPI for the microSD module
- Precision offline timestamping with the DS3231 RTC, ensuring data integrity even without network sync
- Mobile power system design using 18650 lithium cells, an LM2596 buck converter, and TP4056 charging module
- Parsing NMEA GPS sentences to extract location and fix quality, then encoding them into structured SD card logs

Who This Kit Is For
This advanced kit suits final-year B.Tech ECE or EEE students, IoT professionals, and wine industry consultants who need a robust mobile environmental logger. It’s a strong fit for Smart India Hackathon projects requiring geospatial sensor networks or for researchers at IITs, NITs, and BITS Pilani exploring urban heat mapping. Hobbyists with prior ESP32 experience will find it an engaging step beyond basic weather stations.
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?
The AI companion provides step-by-step troubleshooting specific to this kit. You can also reach us on WhatsApp for direct assistance if a step is unclear.
Do I need prior soldering experience?
Yes, this kit requires soldering components onto the prototype boards. The included soldering iron and wire are sufficient, and the AI guide includes clear soldering tips.
Will the GPS module lock inside a building or dense urban area?
The NEO-6M needs a relatively clear sky view. For best results, plan your city walk along open streets or parks; indoor use will not acquire a fix.
How do I turn the logged data into a heat map?
The AI companion provides example Python scripts using free libraries like Folium and Matplotlib to plot GPS-tagged temperatures on an interactive map. No advanced GIS skills required.
