The ESP32 microcontroller acts as the "brain," interfacing with sensors (e.g., DHT11 for humidity, light sensors) and actuators (e.g., relays for appliances).
AWS IoT Core manages device identities, while services like Lambda process data and DynamoDB provides long-term storage. Implementation Workflow 1. AWS Cloud Provisioning
Uses secure MQTT (Message Queuing Telemetry Transport) over Wi-Fi, utilizing port 8883 for encrypted data exchange.
Use the unique AWS IoT Endpoint found in your AWS console settings to establish a secure link.
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 .
To allow your ESP32 to communicate, you must register it as a "Thing" in the AWS console.
