Server Room Temperature Monitor Lab Kit with Arduino Uno + DHT22
Build a Server Room Temperature Monitor with Arduino & DHT22 for Data Centre Cooling Studies
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 walk into a server room, you feel the chill of forced air conditioning. But how much cooling actually comes from evaporation? This kit lets you build a multi-sensor monitor that logs temperature, humidity, and the real-time mass loss of a water dish — exactly like a data centre HVAC engineer would study cooling efficiency. It’s a complete data acquisition system that turns a school project into a meaningful investigation of thermal management.
What You'll Build
A functional sensor array that reads DHT22 temperature and humidity, measures weight change via a 1 kg load cell and HX711 amplifier, timestamps every reading with a DS3231 real-time clock, and displays live data on a 0.96 inch OLED while writing to a microSD card. You'll have a self-contained logger ready for long-duration experiments that mimic the evaporative cooling setups used in data centre research.
What You'll Learn
- Calibrate an HX711 load cell for precision mass measurement under varying temperature and humidity conditions
- Program timing logic with a DS3231 RTC to log sensor data at fixed intervals
- Analyse the relationship between ambient humidity and evaporative mass loss from an open water dish
- Troubleshoot I2C and SPI communication on an Arduino Uno when multiple devices share the bus

Who This Kit Is For
This kit fits squarely into CBSE Class 11–12 physics and computer science investigatory projects, where students need to demonstrate real-world data logging and environmental science concepts. It’s also ideal for ATL Tinkering Lab mentors who want a ready-to-deploy setup for data centre cooling simulations, and for B.Tech ECE/EEE first-year students exploring sensor integration ahead of hackathons like Smart India Hackathon.
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 to access the AI companion, which walks you through wiring, code uploads, and calibration. If you need extra help, our WhatsApp support line is open for this kit.
Can I use this kit for a CBSE physics investigatory project?
Yes, the evaporation mass loss experiment directly aligns with CBSE guidelines for data logging and relationship analysis between humidity and cooling rate.
How do I power the logger for a 24-hour experiment?
Connect the 9V battery snap to the Arduino’s DC jack, and the whole system runs independently without a computer. The microSD card records all data for later analysis.
What if my load cell readings drift over time?
The AI companion includes a calibration routine using the HX711’s tare function and temperature compensation logic, and the included 100nF capacitors reduce noise on the analog line.
Data Centre — HX711 load cell tracks mass loss from open water dish at different temperatures and humidity levels.
