Build a Wireless Server Room Temperature Monitor with Arduino Uno — Live Data Every Second

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Data centres in India — from Bengaluru’s tech parks to Hyderabad’s HITEC City — depend on constant temperature and humidity monitoring to prevent equipment failure. With this kit, you build a compact wireless monitor that streams live environmental readings to a smartphone app every second, exactly the way professional server room dashboards operate. It’s a real-world IoT project that introduces you to sensors, microcontrollers, and Bluetooth communication in one afternoon.

What You’ll Build

You’ll assemble and code a working environmental monitor that uses the DHT11 sensor to measure temperature and humidity, an Arduino Uno to process the data, and an HC-05 Bluetooth module to transmit it all to the Serial Bluetooth Terminal app on your phone. Two LEDs light up when the temperature crosses comfortable thresholds, giving you a visual alert system. When you’re done, you’ll hold in your hand a tool that any data centre manager would recognise—and you’ll have built it from scratch.

What You’ll Learn

• Wire a DHT11 temperature and humidity sensor to an Arduino Uno
• Upload code to read sensor values and transmit them via Bluetooth
• Use the HC-05 module to establish a wireless serial link with a smartphone
• Understand how server rooms prevent overheating using real-time data

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is built for young makers in ATL Tinkering Labs and CBSE Class 6–10 computer science students exploring IoT for the first time. It also serves as an engaging starter project for B.Tech ECE/EEE freshmen at VIT, BITS, NITs, and IITs, and fits neatly into Smart India Hackathon prototyping or a school MakerFest. If you’re a parent or educator looking for a safe, guided introduction to wireless sensors, you’ve found it.

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.
