Server Room Temperature Monitor Kit with ESP32 + Relay
Build an Intelligent Server Room Climate Controller with ESP32-CAM — Cut Energy Waste, Prevent Overheating
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Your small server room or closet holds critical equipment, yet temperature spikes and constant fan noise are a daily worry. This kit turns an ESP32-CAM into a smart eye that sees when people are present, classifies room activity — working, idle, or empty — and automatically adjusts fan speed and lighting via relays. The result is lower energy bills, less wear on cooling hardware, and an OLED always showing vital stats right on the enclosure.
What You'll Build
A wall-mountable unit that uses the ESP32-CAM's image sensor to detect motion and classify room state in real time. When someone enters to work, the lights brighten and the exhaust fan kicks to high. During idle periods, the system scales back; at night, it goes into sleep mode, keeping only a minimal safe airflow. The DHT22 continuously feeds temperature and humidity to a local display, while relay outputs directly control standard AC fans and LED panels.
What You'll Learn
- Running TensorFlow Lite person detection on ESP32-CAM to classify room occupancy
- Wiring and programming a 4-channel relay module to switch AC loads like fans and lights safely
- Interfacing DHT22 sensor and 0.96-inch OLED over I2C for real-time climate display
- Designing a rule‑based automation logic that responds to both thermal thresholds and occupancy events

Who This Kit Is For
IT professionals and network administrators who run small server closets and need a reliable, self‑built monitor. B.Tech ECE and EEE final‑year students working on IoT‑based energy management projects or Smart India Hackathon submissions will find the vision + actuation combo ideal. Also suitable for makerspace mentors looking for an advanced ESP32‑CAM challenge that delivers a practical, wall‑mountable outcome.
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 launch the AI companion trained on this exact project. It can walk you through wiring, code upload, and relay calibration. You can also reach us on WhatsApp for a quick human assist.
Will this work in a dark server closet?
Yes. The ESP32-CAM’s onboard LED flash can be triggered automatically during classification cycles, or you can use an external IR illuminator (not included) if you prefer total darkness.
Can I monitor the server room remotely?
After uploading the provided firmware, the ESP32-CAM hosts a simple web dashboard accessible via the local network. You can view temperature, humidity, and current room state from any browser on the same Wi‑Fi.
What AC load capacity does the relay handle?
The supplied 4-channel relay module is rated for 10A at 250V AC per channel. For typical exhaust fans and LED lighting, this is ample — just ensure your electrician follows standard safety practices.
Data Centre — ESP32-CAM classifies room activity (working, relaxing, sleeping) and adjusts lighting scene and fan via relays.
