Basic IoT Solution Block Diagram and Description

Figure 1 shows a simple IoT solution example.
Figure 1 shows three entities: a light sensor IoT device, a motor controller IoT device (for controlling window
blind opening and closing), and AWS. The light sensor regularly publishes light intensity readings taken at a
certain location. Rule assessments and computations within AWS determine if the window blinds at the same
location should be adjusted.

AWS Summary

In Figure 1 on page 10, AWS services and tools provide:
• A secure bidirectional communication service that provides a publication/subscription broker that uses the
Message Queuing Telemetry Transport (MQTT) protocol.
– Allows light intensity readings to be sent from the light sensor IoT device to AWS.
– Allows motor control information to be sent from AWS to the motor-control IoT device (for adjusting
window blinds).
• State shadowing of the connected IoT devices.
• A rules engine that uses SQL-like syntax for evaluating user-supplied rules.
Rule evaluation can lead to other actions. For example, initiating a computation (using the Lambda service),
sending an MQTT message to an IoT device (for example, to adjust the blinds), pushing notifications to other
Internet-connected devices, etc.
