Example: Device HeartBeat to monitor device connections with Amazon IoT Events

This detector model is one of the templates available from the Amazon IoT Events console. It's included here for your convenience.

The Defective Heart Beat (DHB) example illustrates how Amazon IoT Events can be used in healthcare monitoring. This example shows how you can create a detector model that analyzes heart rate data, detects irregular patterns, and triggers appropriate responses. Learn to set up inputs, define thresholds, and configure alerts for potential cardiac issues, showcasing Amazon IoT Events's versatility in related healthcare applications.
