Wine Cellar Climate Monitor Kit with Arduino Nano + DHT22
Build a Wireless Wine Cellar Climate Monitor with Arduino Nano and DHT22
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Protect your wine collection from temperature and humidity swings that can ruin bottles within weeks. This kit lets you build a two-node wireless monitoring system that displays real-time cellar climate data on an OLED screen and sounds an alarm the moment conditions drift outside the safe range — all without monthly subscriptions or fragile Wi‑Fi dependencies.
What You'll Build
You'll assemble a sensor node with a DHT22 that sits inside your wine cellar, measuring temperature and humidity precisely. It transmits data via NRF24L01 radio to a receiver node anywhere in your home. The receiver shows readings on a crisp 0.96‑inch OLED and triggers an active buzzer if thresholds are breached, giving you instant, audible awareness.
What You'll Learn
- How to interface a DHT22 temperature/humidity sensor with Arduino Nano
- How to establish wireless communication between two Arduino Nanos using NRF24L01 modules
- How to display sensor data on a 0.96‑inch OLED screen
- How to program an active buzzer for audible alerts based on sensor thresholds

Who This Kit Is For
CBSE Class 11‑12 students exploring embedded systems, B.Tech ECE/EEE first‑year learners, and Smart India Hackathon teams prototyping IoT climate monitoring will find this kit directly applicable. It also suits ATL Tinkering Lab activities and hobbyists who want a dependable wireless sensor setup without the hassle of part hunting.
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.

How far can the wireless communication reach?
In open air, the NRF24L01 modules can transmit up to 100 metres. Indoors, through walls, you can expect a reliable range of 25–30 metres — plenty to link a wine cellar to a living room or kitchen.
Can I change the temperature and humidity alert thresholds?
Yes, the pre‑loaded Arduino sketch includes clearly marked variables for upper and lower limits. You can adjust them in minutes to match your wine storage needs, whether it’s 12–14°C for reds or 8–10°C for whites.
Is this kit suitable for a complete beginner?
Absolutely. The build guide assumes no prior experience, and the AI companion explains each connection and code upload. It has been completed successfully by builders as young as 12 with minimal supervision.
