ESP32 HTTPS TLS Client Kit: Build a Secure IoT Sensor Node with Certificate Verification

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

In an era where IoT devices handle sensitive data, secure communication is non-negotiable. With this kit, you’ll build an ESP32 sensor node that reads temperature and humidity from the DHT22, displays readings on the OLED, and makes an HTTPS GET request to a secure API—verifying the server’s TLS certificate every time. This isn’t just another sensor project; it’s a practical lesson in encrypting data in transit and protecting your IoT infrastructure from downgrade attacks.

What You'll Build

A working IoT sensor that establishes an HTTPS client connection with full TLS certificate verification, fetches or sends data to a secure endpoint, and displays system status on the OLED. You’ll have a functional node you can reuse in any secure IoT gateway, industrial monitoring setup, or college project.

What You'll Learn

• Setting up HTTPS client on ESP32 using Arduino IDE
• Implementing TLS certificate verification (root CA and pinning)
• Interfacing DHT22 sensor and I2C OLED display
• Structuring secure IoT firmware with error handling
