Server Room Temperature Monitor Pro Kit with Arduino Mega + DHT22
Server Room Temperature Monitor Pro Kit with Arduino Mega & DHT22: 8-Sensor Data Centre Guardian
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a blank PCB into a professional-grade server room monitoring dashboard that tracks temperature, humidity, current load on two circuits, barometric pressure, and time-stamps logs to SD card — all controlled through a vivid 2.4-inch touchscreen. When thresholds breach, the built-in relay module automatically triggers external cooling or alert systems, making it a real-world solution for small data centres, networking closets, and enterprise labs.
What You'll Build
You'll assemble and program a wall-mountable DIN rail unit that displays eight live sensor gauges on a TFT screen: two ambient temperature channels (DHT22), humidity, atmospheric pressure (BMP280), two separate AC/DC current consumption readings (ACS712), and system uptime via DS3231 real-time clock. Touch buttons on the screen let you manually turn relays on/off for direct control of external fans, sirens, or backup units.
What You'll Learn
- Calibrating multiple sensor modules (DHT22, BMP280, ACS712) on Arduino Mega simultaneously
- Driving a TFT ILI9341 display with touch interface using optimized libraries
- Implementing real-time data logging to MicroSD and RTC timekeeping
- Designing relay logic for automated environmental control and alarm triggering

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE students undertaking capstone projects, Smart India Hackathon participants prototyping industrial-grade monitoring systems, and IIT/NIT/VIT/BITS lab researchers setting up small-scale data centres or server rooms. Diploma and polytechnic instructors will also find it a ready-to-use teaching module for industrial instrumentation and control.
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 inside the box to access your AI build companion, trained on this exact project wiring and code. You can also reach us via WhatsApp for human support within 6 hours.
Can I monitor the system remotely or access logs without physically touching the TFT display?
Yes, the MicroSD module stores CSV logs with timestamps via DS3231, which you can later transfer to a PC. For live remote monitoring, advanced users can add an Ethernet shield or ESP8266 module (not included) to push data to a web dashboard.
Is soldering difficult for a beginner? The kit includes a soldering iron.
This project requires soldering through-hole components onto PCB prototype boards. The included soldering iron and wire are high-quality, but if you're completely new to soldering, our AI companion includes video guidance. For a solderless experience, you can use breadboards (not included) for prototyping, though the final industrial-grade build needs soldering.
How do I ensure the ACS712 current sensors are accurate for 230V AC server loads?
The two ACS712 5A modules are non-invasive; you'll connect them in series with the load lines. Calibration involves setting a zero-current offset in code. The AI companion includes a calibration routine. For high-voltage safety, consult an electrician if you're not comfortable with mains wiring.
Data Centre — Mega with TFT touch shows 8 sensor gauges. Relay control from touch buttons on screen.
