Server Room Temperature Monitor Kit with ESP32 + DHT22 v12
ESP32 Server Room Temperature Monitor Kit with DHT22 v12: Build a Private IoT Monitoring System for Data Centres
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 professional-grade environmental monitor for server rooms or data centres. This ESP32-based system measures temperature and humidity using the DHT22 v12 and atmospheric pressure with the BMP280, tunnelling all telemetry data through a self-hosted WireGuard VPN for a completely private IoT network. Once deployed, you'll have a dash-less monitoring solution with local OLED display and remote MQTT access—without exposing your data to public clouds.
What You'll Build
A secure, self-contained temperature, humidity, and pressure monitor that streams encrypted data to your own MQTT broker over a WireGuard tunnel. You'll assemble the hardware on a prototype PCB, load the firmware, configure VPN credentials, and mount the unit in a rugged enclosure. The result is a data centre-grade device that you can manage entirely within your private network.
What You'll Learn
- Setting up a WireGuard VPN server and client on ESP32 for end-to-end encryption
- Publishing DHT22 and BMP280 sensor data over MQTT through an encrypted tunnel
- Soldering and assembling a permanent prototype on PCB with proper decoupling
- Configuring async MQTT with watchdog timers for 24/7 uptime in critical environments

Who This Kit Is For
This kit is designed for engineering students building capstone projects in secure IoT, participants of Smart India Hackathon focusing on data centre monitoring, and early-career professionals prototyping an in-house server room monitoring system. If you're pursuing B.Tech in ECE/EEE at NIT, VIT, or BITS and need a ready-to-deploy project with enterprise-level encryption, this kit has everything you need.
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?
The AI companion accessible via QR code walks you through every step; you can also reach us on WhatsApp for direct troubleshooting.
Do I need to set up my own WireGuard server?
Yes, you'll provision a cloud VM or use an existing VPN server. The kit includes configuration guides for common providers like DigitalOcean and AWS Lightsail, with AI companion support for setup steps.
Can I monitor multiple server rooms with one dashboard?
MQTT data from this sensor can be piped into Grafana or Node-RED. Our build guide shows integration with InfluxDB to create multi-sensor dashboards on a single instance.
What happens if a component fails after assembly?
We offer a 7-day replacement guarantee for any manufacturing defect. Contact us via WhatsApp and we'll ship a replacement component promptly.
Data Centre — ESP32 connects to Wireguard VPN server. All MQTT traffic tunnelled through VPN for private IoT network.
