Server Room Temperature Monitor Mini Kit with ESP32 + DHT22
Build a Cloud-Connected Server Room Temperature Monitor with ESP32 and AWS IoT
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a server room where temperature and humidity are silently monitored 24/7 and every spike is recorded in the cloud — without a single human checking a gauge. This kit puts you in the driver's seat of that system. You'll assemble a sensor node that uses an ESP32 to read environment data from DHT22 and BMP280 sensors, then securely posts it via HTTPS to an AWS API Gateway endpoint, where a Lambda function logs it into a DynamoDB table you create. The onboard OLED shows local readings in real time, so you can verify the node is live before stepping away.
What You'll Build
A compact, battery-friendly monitor that measures temperature, humidity, and barometric pressure inside a data centre or server room. The ESP32 establishes a Wi-Fi connection, encrypts sensor readings, and sends them to a cloud endpoint you configure. All data flows into a persistent DynamoDB table — ready for custom dashboards or alerting later. You'll assemble the unit inside a durable enclosure and test it under realistic conditions.
What You'll Learn
- Configure the ESP32 to connect to Wi-Fi and perform HTTPS POST requests with TLS encryption
- Interface DHT22 and BMP280 sensors to capture temperature, humidity, and pressure accurately
- Set up AWS services: create an API Gateway, write a Lambda function, and store data in DynamoDB
- Solder and assemble a deployable sensor node with an OLED display for local readout

Who This Kit Is For
Advanced engineering students — B.Tech ECE, EEE, or Computer Science at IITs, NITs, VIT, BITS Pilani — who need a real-world IoT project for their resume or Smart India Hackathon prototype. It is also ideal for CBSE Class 11-12 students preparing for national-level competitions with a strong electronics and coding focus, and for ATL Tinkering Labs mentors wanting a ready-made AWS IoT workshop resource.
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 launch your AI companion, which walks you through every wiring step and code upload. If you need a human hand, send a photo of your setup on WhatsApp and get a reply within hours.
Do I need an AWS account to complete the project?
Yes, you'll need an AWS Free Tier account. The AI guide includes screenshots and exact IAM policy snippets to configure API Gateway, Lambda, and DynamoDB securely without incurring costs.
Will the monitor work without internet if the server room Wi-Fi drops?
The ESP32 buffers a few readings and retries posting when the network comes back. The OLED always shows the latest sensor values locally, so you can still read them on-site even during an outage.
How do I mount the enclosure in a server rack?
The enclosure has pre-drilled slots for cable ties and a magnetic base option. We include a mounting guide that shows common rack post spacing and vented panel placements.
Data Centre — ESP32 sends HTTPS POST to API Gateway which triggers Lambda function to log data to DynamoDB.
