Wine Cellar Climate Monitor Kit v18
Wine Cellar Climate Monitor Kit v18 — Build a 5-Year Battery-Powered LoRa Sensor for Wine Storage
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a battery-powered climate monitor for your wine cellar that wirelessly transmits temperature and humidity data via LoRa to your dashboard. The ATSAMD21 microcontroller deep-sleeps between hourly transmissions, achieving a 5-year runtime on a single CR123 battery. This kit turns accurate environmental sensing into a maintenance-free, long-term solution for wine storage.
What You'll Build
You’ll assemble a compact, waterproof sensor node that sends real-time wine cellar conditions to a central LoRa gateway. The node pairs a DHT22 for humidity and a BMP280 for precision temperature and pressure, communicating over the RA-02 LoRa module. Housed in a sealed enclosure and powered by a CR123 battery, it provides years of unattended monitoring critical for preserving wine quality.
What You'll Learn
- Programming the ATSAMD21 for ultra-low power deep sleep modes to achieve multi-year battery life.
- Interfacing the DHT22 and BMP280 sensors over I2C and one-wire protocols for accurate climate data.
- Setting up LoRa communication using the RA-02 module and 433MHz antenna for long-range wireless transmissions.
- Designing a battery-powered IoT device with minimal power consumption and reliable interval-based data logging.

Who This Kit Is For
This advanced kit is designed for B.Tech ECE/EEE students tackling IoT and embedded systems coursework, Smart India Hackathon teams needing reliable long-range sensor nodes, and experienced hobbyists comfortable with soldering and microcontroller coding. It also fits into ATL Tinkering Labs with advanced tooling and college engineering clubs running environmental monitoring projects.
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 for your AI companion that walks you through every step, or message us on WhatsApp for direct engineer support.
Does this kit include the LoRa gateway or receiver?
The kit contains the transmitter (sensor node) only. You’ll need a compatible LoRa receiver, such as another RA-02 module or a LoRaWAN gateway. The AI companion includes guidance on setting up a simple receiver with an additional Arduino.
Can this sensor be placed outdoors?
The waterproof enclosure is rated for humid indoor environments like a cellar. For outdoor use, add extra sealing; the electronics and CR123 battery operate reliably from -20°C to 60°C.
What programming experience is required?
You should be comfortable with Arduino IDE and C/C++. Deep sleep and LoRa library configuration are advanced topics, but the AI companion provides tailored code examples and explanations for each component.
Wine Storage — ATSAMD21 + RA-02 LoRa. Deep sleep between transmissions. CR123 battery lasts 5 years transmitting hourly.
