In this lab, you will run a simple IoT device simulator on Amazon Elastic Compute Cloud (Amazon EC2) that will send sensor data (temperature) to the AWS IoT device gateway. You will then build a simple rule, using SQL-like syntax, that will publish a notification to an Amazon Simple Notification Service (Amazon SNS) topic when the temperature of the device is within a defined threshold. By connecting your email address with the Amazon SNS topic, you will receive an email notification when the threshold is met. Finally, you will update the device shadow, instructing the device to "turn on the air conditioning," resulting in lowering temperatures.

Level

Fundamental

Duration

1 Hours 30 Minutes

Course Objectives

In this course, you will learn how to:

• Create AWS IoT certificates and keys
• Run the simulator app and publish data to AWS IoT
• Subscribe to the topic with the MQTT client in the AWS Management Console and watch the data stream in
• Create an AWS IoT rule that will look for records with a temperature above a defined threshold
• Associate a Simple Notification Service action with the rule
• Publish a state change to the device shadow, instructing the simulator app to reduce temperature by "turning on the air conditioning"

Intended Audience

This course is intended for:

• Architects
• Developers

Prerequisites

We recommend that attendees of this course have the following prerequisites:
