Build a Professional-Grade Server Room Temperature Monitor with ESP32 and DHT22

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

This kit gives you everything needed to build a real-world IoT device that monitors ambient temperature inside a server room or data center. The ESP32 reads the DHT22 sensor, displays values on the OLED, and then performs an HTTPS GET request to a secure API endpoint with full TLS certificate verification. It is a complete, end-to-end exercise in safe IoT data transmission — exactly the technique used by modern infrastructure monitoring systems to prevent man-in-the-middle attacks.

What You'll Build

You will assemble a standalone temperature monitor that logs readings locally on a crisp OLED screen and pushes them to a remote server over an encrypted connection. The ESP32 automatically connects to your Wi-Fi, acquires the DHT22 measurement every few seconds, and sends the data payload to a configurable HTTPS endpoint after verifying the server's root CA certificate. The display shows the current temperature, humidity, and the last HTTP response code, giving you live feedback on the health of your monitoring pipeline.

What You'll Learn

• Configuring an ESP32 to make HTTPS GET requests with root CA certificate verification
• Interfacing the DHT22 temperature and humidity sensor with an I2C OLED display
• Handling TLS certificate chains to ensure end-to-end secure IoT communication
• Structuring a modular data logging system with WiFi connectivity and error handling

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit is ideal for CBSE Class 11–12 students pursuing computer science or IP, where secure networking concepts are now part of the syllabus. B.Tech ECE and EEE undergraduates building proof-of-concept IoT nodes for projects or hackathons like Smart India Hackathon will find the TLS integration directly relevant. ATL Tinkering Lab facilitators and IIT/NIT/VIT/BITS students working on campus infrastructure prototypes can use the kit as a ready-made secure sensor gateway.

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.
