Setting up Amazon IoT

To complete this tutorial, you need to create the following resources. To connect a device to Amazon IoT, you create an IoT thing, a device certificate, and an Amazon IoT policy.

  • An Amazon IoT thing.

    A thing represents a physical device (in this case, your Rasberry Pi) and contains static metadata about the device.

  • A device certificate.

    All devices must have a device certificate to connect to and authenticate with Amazon IoT.

  • An Amazon IoT policy.

    Each device certificate has one or more Amazon IoT policies associated with it. These policies determine which Amazon IoT resources the device can access.

  • An Amazon IoT root CA certificate.

    Devices and other clients use an Amazon IoT root CA certificate to authenticate the Amazon IoT server with which they are communicating. For more information, see Server authentication.

  • An Amazon IoT rule.

    A rule contains a query and one or more rule actions. The query extracts data from device messages to determine if the message data should be processed. The rule action specifies what to do if the data matches the query.

  • An Amazon SNS topic and topic subscription.

    The rule listens for moisture data from your Raspberry Pi. If the value is below a threshold, it sends a message to the Amazon SNS topic. Amazon SNS sends that message to all email addresses subscribed to the topic.
