New AWS IoT Tools for Visual Building, Event Detection Go Live

Amazon Web Services (AWS) last week announced the "live" release of two new Internet of Things (IoT) services it had previously announced back in November 2018 at its re:Invent conference.

AWS IoT Things Graph is designed to let developers "easily" build IoT applications "visually." Business logic is represented via "flow," a "model" is used for the Web services and devices, and then actions, events and states can be added to those models. There are also mappings for bringing the flow and converting the output (which can go to either the AWS cloud or AWS IoT Greengrass, Amazon's IoT platform for smart edge computing).

The tool is aimed at both consumer and industrial IoT uses. It offers prebuilt models for a "number" of devices (including switches, camera motion sensors and Web services like Amazon Rekognition and Amazon S3), or developers can of course create their own.

Models are reusable and combinable.

Post-launch, IoT Things Graph "coordinates interactions between devices and Web services and retries any failed steps to keep your workflow running smoothly," AWS explained. "While your application is running, you can track metrics, set alarms, view logs files, and watch real-time status updates."

More details and screenshots of exactly how AWS IoT Things Graph works can be found here. Pricing details are here.

The other new tool, AWS IoT Events, is designed to "detect the state of anything and take action."

Example events cited by the company include everything from stuck conveyor belts to temperature changes to misaligned robotic arms or simply motion after-hours.

Developers can create "detector modules" to represent device states and transitions, and then trigger "actions" when "critical events" are detected by the system.

The company explains that AWS IoT Events lets developers "build robust, highly automated systems. Actions can, for example, send a text message to a service technician or invoke an AWS Lambda function."

Detailed screenshots of how the system works can be found further down on this page. Pricing details can be found here.
