Build a Wine Cellar Climate Monitor with Arduino Nano & NRF24L01 — Intro to 2.4GHz Wireless

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 wine cellar’s ideal environment—steady 12–14°C and 60–70% humidity—is critical for aging wine. With this kit, you’ll build a two-node system that sends real-time temperature and humidity readings from a sensor node to a display node up to 100 metres away, using 2.4GHz NRF24L01 radios. No wires, no cloud account—just raw, reliable radio communication you can see on the OLED screen.

What You'll Build

You’ll assemble a sensor node with a DHT22 and an Arduino Nano that transmits data every few seconds. On the receiver side, another Nano with an OLED display instantly shows the wine cellar’s climate. You’ll understand how radio packets are structured, how to pair two NRF modules, and how to debug signal loss.

What You'll Learn

• Setting up an NRF24L01 radio for 2.4GHz communication
• Reading accurate temperature and humidity from a DHT22 sensor
• Displaying live data on a 0.96-inch OLED using I2C
• Basic troubleshooting of wireless data transmission (range, interference, antenna orientation)

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for absolute beginners aged 5–15 (with adult supervision for builders under 12) who want their first real-world wireless project. It fits perfectly into ATL tinkering labs, CBSE Class 9–12 electronics projects, and B.Tech ECE mini-projects at VIT, BITS, or NITs. The wireless communication component aligns with Smart India Hackathon hardware prototypes and IoT internships. If you’ve never touched an NRF module or an OLED, the AI companion walks you through every connection.

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.
