Wine Cellar Climate Monitor Kit with ESP32 + DHT22 v7
Wine Cellar Climate Monitor Kit with ESP32 + DHT22 v7 — 6 Months of Monitoring on a Single Battery
Every part needed for a long-running wine cellar climate monitor, pre-tested for deep-sleep compatibility, with an AI companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Your prized wine collection demands stable temperature and humidity, but you can’t babysit a cellar. This kit lets you build a Wi‑Fi climate sentinel that wakes hourly, pings your phone with DHT22 readings, and then slips back into a sleep so deep it sips mere microamps. All it needs is the included 500 mAh LiPo—no wires, no wall adapters—for six months of uninterrupted vigilance.
What You'll Build
You'll assemble a breadboard‑based monitor that uses the ESP32-C3’s ULP co‑processor to schedule precision wake‑ups. Every cycle the DHT22 captures temperature and humidity, the data shoots to a Blynk dashboard over Wi‑Fi, and the system returns to deep sleep. The TP4056 module keeps the battery topped off when you do plug in, while the entire circuit stays portable enough to tuck into a wine rack corner.
What You'll Learn
- Programming the ESP32-C3’s Ultra‑Low‑Power (ULP) co‑processor for autonomous wake‑up cycles
- Integrating a DHT22 humidity/temperature sensor without disrupting deep sleep states
- Calculating and optimizing battery life for continuous IoT node operation
- Designing a self‑contained monitoring prototype ready for permanent deployment

Who This Kit Is For
CBSE Class 11–12 students diving into IoT will find a perfect balance of hardware and low‑power coding. B.Tech ECE/EEE learners prepping for Smart India Hackathon or capstone projects can master ULP design quickly. ATL Tinkering Lab mentors and hobbyist wine collectors get a ready‑to‑go sensor node that solves a real‑world problem without endless component 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.
What if I get stuck during the build?
Scan the QR code to chat with our AI companion; it knows every pin connection and code snippet. You can also ping us on WhatsApp for a human reply.
Will this kit really run for six months on the included battery?
Yes. With the provided deep‑sleep firmware, the system draws less than 1.5 mAh per day. The 500 mAh LiPo easily exceeds 300 days in testing—we claim six months to leave margin.
Can I log data to a cloud dashboard?
Absolutely. The project includes a Blynk example that graphs temperature and humidity live. You can modify it to send data to ThingSpeak, Adafruit IO, or your own MQTT broker.
Do I need to solder anything?
No soldering. The ESP32-C3 Super Mini and TP4056 module come with pre‑soldered headers, and all connections use the included breadboard and jumper wires.
Wine Storage — ESP32-C3 reads DHT22 in deep sleep wake cycle using ULP co-processor. 6 month coin cell battery life.
