01 - AWS Serverless IoT: A Synchronous IoT Dashboard

День тому

In this video we create an Action and Rule in AWS IoT Core which sends data to a S3 bucket we are using as a static web host. No additional storage is needed for this simple design as we use the same S3 bucket for both storage and static website hosting.
We utilize is a Highcharts visualization hosted on S3 that works with an IoT Core action that saves data to S3. The JavaScript code in the S3 webhost fetches the IoT data in the S3 bucket and synchronously charts the resultant data points for each fetch interval. The cost should be a few pennies if you are off the free tier.

Is there a way to send json data packets with specific names and under specific folders? For example, if I have 3 unique folders for 3 different users. I want to send user1's data to their folder, user2's to their, etc. Also I want to send two different types of data. For example one coming from temp sensor, the other coming from soil moisture sensor. Is there a way to put and read each data packet with a name+timestamp? User1: TempSensor readings --> s3Bucket/user1folder/tempsensorReading+timestamp Soil Moisture --> s3Bucket/user1folder/SoilSensorReading+timestamp User2: TempSensor readings --> s3Bucket/user2folder/tempsensorReading+timestamp Soil Moisture --> s3Bucket/user2folder/SoilSensorReading+timestamp Etc

You can send IoT Data to AWS IoT Core with different topic identifiers or have the user identify themselves in the JSON IoT Payload as a key value pair. To distribute those payloads you would need to check that the topic or payload match the key-value pai either the Rules query statement or in a Lambda function 'rule action' linked to IoT Core. From there the data can easily be dispatched to a folder or any other service you like.

Hi Steve , how can we send data from sensors in real time to cloud using these AWS services

@SteveOnIoT Рік тому

The traditional way is to write server side code like hosting an MQTT broker and database application in a Linux instance in AWS EC2. However, I show you how to do it using AWS Serverless services with WebSockets later in this lecture series. Propagation varies depending on your distance from AWS region datacenter but I am getting 4/5 of a second latency from the west coast to US-East-1.

Hi Steve, is there any way to allow the chart to show historical data after refreshing the website? Because upon refreshing the website, the data on the chart reset as well. Thank you

Yes but it is not trivial. You would need to store the data in a data repository like S3 or DynamoDB. The easiest way is to use DynamoDB as an IoT data repository created in a separate Rule from IoT Core. Then you can use Lambda to fetch the data from Dynamo via a user SQL statement from a GET request to the Lambda function URL from your web code. If you wanted to pass query parameters from you web code for specific search criteria you would also need API Gateway to interface your Lambda function.
