ESP32 SNMP Wine Cellar Monitor Kit: Temperature & Humidity with OLED
ESP32 SNMP Wine Cellar Climate Monitor Kit - Real-Time Temperature & Humidity Over UDP
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Wine cellars demand stable temperature and humidity - a single spike can spoil an entire collection. With this kit you build an ESP32-powered monitor that not only displays conditions locally but also acts as a full SNMP agent, making sensor readings queryable over UDP by any network management system. From a Zabbix dashboard to a custom NMS, you get real-time environmental visibility exactly where it matters.
What You'll Build
You'll assemble a compact sensor board combining DHT22 for temperature/humidity, ACS712 for current monitoring, and a 0.96-inch OLED for local readout. The ESP32 runs an embedded SNMP agent with custom MIB variables - walk the OID tree from a laptop, visualise trends, or trigger alerts when cellar conditions drift outside safe ranges. It's a complete network-monitorable climate node you can deploy in minutes.
What You'll Learn
- Configuring an ESP32 as an SNMP agent with custom MIB variables for environmental data
- Interfacing DHT22 and ACS712 sensors over I�C and analog, then calibrating readings
- Implementing UDP-based query-response protocol for remote network monitoring
- Driving a 0.96-inch OLED from the ESP32 to show live temperature, humidity, and current

Who This Kit Is For
Students in CBSE Class 11-12 exploring networking and IoT, B.Tech ECE/EEE learners working on SNMP-based industrial monitoring, Smart India Hackathon teams building smart infrastructure, and ATL Tinkering Labs introducing enterprise protocols find this kit exactly at their level. Even hobbyist wine collectors with a technical bent can deploy a professional-grade monitor in their own cellar.
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 the AI companion; it diagnoses issues specific to this kit. If you need a human, our team replies on WhatsApp within hours.
Do I need prior SNMP knowledge?
No. The guide introduces MIB, OIDs, and UDP communication from scratch, so even if you've never used SNMP you'll have a working agent by the end.
Can this monitor an actual wine cellar?
Yes. Once assembled and calibrated, the DHT22 covers typical cellar temperature (10-15 �C) and humidity (60-70% RH). The ACS712 can track cooler unit current if you wire it in series.
Does the kit require soldering?
Yes. The included soldering iron and wire let you assemble the PCB board. The AI companion includes short video tutorials if you're new to soldering.
Wine Storage - ESP32 implements SNMP agent exposing MIB variables for sensor readings. NMS queries over UDP.
