Server Room Temperature Monitor Mini Kit with Arduino Uno + DHT22
Build a Server Room Temperature Monitor with Arduino Uno & DHT22: LCD Menu, 4 Relay Outputs
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a server room where temperature spikes are detected instantly, and cooling fans or backup AC units turn on automatically via a custom LCD menu. With this kit, you’ll build a fully functional temperature monitor that can control up to four appliances by name—simulating real data center cooling management.
What You'll Build
You’ll assemble a compact system that reads ambient temperature from a DHT22 sensor, displays it on a 16x2 LCD screen, and lets you navigate a menu using tactile buttons to manually toggle or schedule cooling devices connected to four relays. The final build can be installed in a mock server rack or used as a proof-of-concept for your engineering project.
What You'll Learn
- Interfacing DHT22 temperature/humidity sensor with Arduino
- Creating menu systems with LCD and push buttons
- Driving high-voltage appliances safely via relay modules and flyback diodes
- Implementing temperature-threshold logic for automatic control

Who This Kit Is For
This kit is ideal for CBSE Class 11-12 students working on computer science or physics projects, B.Tech ECE/EEE undergraduates developing an IoT-based temperature controller, and ATL Tinkering Labs looking for a realistic industrial automation challenge. If you’re participating in Smart India Hackathon or need a mini project for IIT/NIT/VIT/BITS curriculum, this kit gives you a ready-to-go hardware platform.
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 scans the QR code in the box, giving you visual, step-by-step instructions for every connection. If you need human help, WhatsApp support connects you directly with our project engineers.
Can I use this to control actual 230V appliances?
Yes, the relay module can switch loads up to 250V AC at 10A. For safety, always disconnect mains power before wiring and never touch live terminals. The included flyback diodes protect the Arduino from relay coil surges.
Does this kit require soldering?
No soldering is needed. All components plug into the provided 400‑point breadboard using male‑male jumper wires, making the build completely solderless and reusable.
Can I log temperature data to a computer?
The firmware displays real‑time temperature on the LCD. You can extend the project by adding an SD card module or Bluetooth (not included) to log data; the AI companion provides optional integration code.
Data Centre — LCD menu controls 4 relay appliances by name. DHT22 shows room temperature.
