ESP32 Server Room Temp Monitor Kit
mDNS Hostname Access
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When you need to check the temperature inside a server room or data centre rack, you don't want to remember IP addresses. This kit lets you build a web-connected temperature monitor that registers a friendly hostname-compoden.local-so any browser on your local network can reach it just by typing that name. No IP hunting, no configuration headaches.
What You'll Build
A compact, network-connected device that reads ambient temperature and humidity from a DHT22 sensor, then displays the readings on a simple web page accessible from any phone, tablet, or PC on the same network. Just open a browser and go to compoden.local. Two LEDs indicate power and alert thresholds, giving you a quick visual check without opening a browser.
What You'll Learn
- Configure an ESP32 as a Wi-Fi connected web server that serves live sensor readings
- Register an mDNS hostname (compoden.local) so your device is accessible by name, not IP
- Interface a DHT22 digital temperature and humidity sensor and read its data
- Wire a complete circuit on a breadboard with status LEDs and understand basic electronics flow

Who This Kit Is For
CBSE Class 11-12 students exploring IoT and networking basics, B.Tech first-year ECE/EEE students building their first mini project, and ATL Tinkering Lab teams who want to monitor their lab's server rack temperature. Anyone curious about how devices on a local network can be reached by a name instead of an IP address will find this kit instantly rewarding.
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 on the box to launch the AI companion, which gives step-by-step guidance for this specific kit. You can also send a WhatsApp message to our support team for hands-on help.
Do I need to know coding?
No prior coding is required. The kit includes pre-written firmware that you flash to the ESP32 using a simple desktop tool. The AI companion explains every step of the process.
Can I access the monitor from outside my local network?
The compoden.local hostname works only within your Wi-Fi network. If you want remote access, you can later extend the project with port forwarding or a cloud service, but that is beyond the scope of this kit.
What if my network doesn't support mDNS?
Most home and office routers support mDNS out of the box. If yours does not, the serial monitor displays the ESP32's IP address so you can still open the web page directly by typing that IP.
Data Centre - ESP32 registers compoden.local mDNS hostname. Any browser on local network finds it by name not IP.
