Server Room Temperature Monitor Plus Kit with ESP32 + DHT22
Build a Self-Hosted Server Room Environment Monitor with ESP32, DHT22, and Relay Control
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 demand constant environmental monitoring, but cloud dependencies introduce latency and security risks. This kit lets you build a complete local monitoring system that logs temperature, humidity, and pressure, triggers relay‑controlled alarms, and displays historical charts — all without any internet connection. The ESP32 acts as its own web server, giving you a private dashboard accessible only within your local network.
What You'll Build
You will assemble and program a hardware device that hosts its own web dashboard over Wi‑Fi, displaying real‑time data from two DHT22 sensors and a BMP280. The finished unit sits inside a server rack, continuously tracks ambient conditions, and activates relays when predefined thresholds are breached — all while logging every reading to a MicroSD card with precise RTC timestamps.
What You'll Learn
- Integrating multiple I2C and one‑wire sensors on the ESP32 platform.
- Building an asynchronous web server that serves dynamic charts and control interfaces.
- Implementing non‑volatile data logging to a MicroSD card with DS3231 RTC timestamps.
- Designing power‑efficient circuits with buck converters and noise suppression for industrial environments.

Who This Kit Is For
This kit targets B.Tech ECE, EEE, and CSE students working on IoT internships or final‑year projects at institutes like IIT, NIT, VIT, or BITS Pilani. It is equally valuable for Smart India Hackathon teams building reliable sensor systems and for advanced lab mentors guiding embedded systems builds. If you need a self‑contained, industrial‑grade monitoring proof‑of‑concept, this is your starting point.
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 start a chat with the AI build companion trained on this exact server room monitor project. If you need human help, our team is available via WhatsApp at the same number.
Does this kit require internet access to view sensor data?
No. The ESP32 creates its own Wi‑Fi access point; you connect your phone or laptop directly to the dashboard. All charts and logs are served locally, with zero dependency on any external network.
Can I add more sensors or control additional relays?
Yes. The ESP32 has spare GPIOs and an I2C bus. The AI companion includes guidance on expanding the system with extra DHT22 units or actuators, and the modular prototype board gives you room to grow.
How do I power the monitor inside a server rack?
The included 5V 2A supply plugs into any standard UPS‑backed outlet. Combined with the LM2596 buck converter, the unit handles voltage fluctuations gracefully and runs continuously without brown‑out resets.
Data Centre — ESP32 runs a complete web server with charts, sensor readings and relay control. No internet required.
