Server Room Temperature Monitor Kit with Arduino Uno + DHT22 v3
Server Room Temperature & Humidity Monitor Kit with Arduino Uno – Live XY Scatter Plot & Correlation
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 compact monitor that reads temperature from two sensors—DHT22 for humidity & temperature, BMP280 for precise pressure-derived temperature—and plots their relationship as an XY scatter graph on a colour TFT. The system calculates the Pearson correlation coefficient in real time, mimicking the kind of health metrics used in data centre environment monitoring.
What You'll Build
You'll assemble a self-contained monitoring device that displays ambient temperature, humidity, pressure, and the live statistical correlation between two temperature readings. It logs timestamped data using a DS3231 real-time clock, giving you a portable tool to evaluate air mixing and hot spots in server racks.
What You'll Learn
- Interfacing digital temperature/humidity sensors (DHT22, BMP280) with Arduino
- Plotting live XY scatter graphs on a TFT display
- Calculating Pearson correlation coefficient from sensor arrays
- Using a real-time clock module for precise data timestamping

Who This Kit Is For
This intermediate kit is ideal for CBSE Class 11-12 students exploring data logging and statistics, B.Tech ECE/EEE students prototyping environmental monitoring solutions for Smart India Hackathon, and tinkerers at ATL labs or college clubs who want a real-world industrial simulation of server room health checks.
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 chat with the AI companion, which has every wiring diagram and code snippet. If you need a human, write to us on WhatsApp for direct help.
Do I need prior Arduino experience to build this kit?
Basic familiarity with Arduino IDE and breadboarding helps. The AI companion includes setup guides and a full code walkthrough tailored to this intermediate project.
Can this monitor be used for actual server room monitoring?
It’s a working prototype and an excellent learning tool. You can extend it—add an SD card module for data logging or external probes—to adapt it for real-world use.
What does the Pearson correlation show in this project?
It measures how closely the two temperature readings move together. A strong positive correlation can indicate uniform cooling; a drift might reveal sensor placement issues or hot spots.
