AWS IoT Core manages device identities, while services like Lambda process data and DynamoDB provides long-term storage. Implementation Workflow 1. AWS Cloud Provisioning
Trigger functions to run logic (e.g., "if temperature > 30°C, send an alert").
Once data reaches AWS IoT Core, you can route it to other services using : Building Complete IoT Solution with ESP32 and A...
Embed your downloaded certificates directly into your code or store them in the ESP32's LittleFS/SPIFFS filesystem . 3. Firmware Development The ESP32 firmware should perform three main tasks:
AWS will generate a Device Certificate, a Private Key, and an Amazon Root CA . These are essential for the SSL/TLS handshake and must be stored securely. 2. Development Environment Setup Most developers use the Arduino IDE or PlatformIO . AWS IoT Core manages device identities, while services
The ESP32 microcontroller acts as the "brain," interfacing with sensors (e.g., DHT11 for humidity, light sensors) and actuators (e.g., relays for appliances).
Publish sensor data to a specific topic (e.g., esp32/sensor/data ) and subscribe to a command topic to receive instructions from the cloud. 4. Backend Processing & Visualization Once data reaches AWS IoT Core, you can
Create a unique identity (e.g., "MyESP32Device").
