DynamoDB Stream + Amazon ES (ElasticSearch, Kibana) [P024]




* Parts

- Raspberry Pi 

- AWS Lambda Java Project in Ecplise


* Contents

1. Upload sensor data to json file using the Amazon S3 Rest API

Pi4J + Amazon S3 REST API + Amazon Athena [P019]



2. Amazon Lambda S3 Trigger (node.js) : S3toDynamoDB

- source code : https://github.com/rdiot/rdiot-p022/blob/master/S3toDynamoDB/index.js

'use strict';

console.log('RDIoT S3toDynamoDB Loading post function');

var AWS = require('aws-sdk'); 

var s3 = new AWS.S3();

var dynamo = new AWS.DynamoDB.DocumentClient();


exports.handler = function(event, context, callback) {

    console.log('Received event:', JSON.stringify(event, null, 2));

    var bucket = event.Records[0]['s3']['bucket']['name'];

    var en = event.Records[0]['eventName'];

    var et = event.Records[0]['eventTime'];

    var key = event.Records[0]['s3']['object']['key'];

    var sip = event.Records[0]['requestParameters']['sourceIPAddress'];


    var params1 = {Bucket: bucket, Key: key}; 

    s3.getObject( params1, function(err,data) {

        if(err) {

            console.log(err.stack);

            callback(err);

        } else {

            var value = data.Body.toString('ascii')

            console.log(data);

            console.log("Raw text:\n" + value);


            var params2 = {

                TableName: "pi-sensor",

                Item:{

                    "id": et,

                    "event" : en,

                    "bucket": bucket,

                    "key" : key,

                    "sip": sip,

                    "value" : value

                }

            };

            console.log("Gettings IoT device details...");


            //S3 to DynamoDB

            dynamo.put(params2, function(err, data) {

                if(err) {

                    console.error("Unable to post devices. Error JSON:", JSON.stringify(err, null, 2));

                    context.fail();

                } else {

                    console.log("keepet data:", JSON.stringify(data, null, 2));

                    context.succeed('success post');

                }


            });

        }

    });

}


3. AWS DynamoDB Monitoring




4. Create IAM Role

- It must have basic Amazon ES, DynamoDB, and Lambda execution permissions

- create custom role name : LambdaDynamoDBtoES


{

  "Version": "2012-10-17",

  "Statement": [

    {

      "Effect": "Allow",

      "Action": [

        "es:ESHttpPost",

        "es:ESHttpPut",

        "dynamodb:DescribeStream",

        "dynamodb:GetRecords",

        "dynamodb:GetShardIterator",

        "dynamodb:ListStreams",

        "logs:CreateLogGroup",

        "logs:CreateLogStream",

        "logs:PutLogEvents"

      ],

      "Resource": "*"

    }

  ]

}


5. Setup Amazon ES (Elasticsearch + Kibana)

- Define domain

- Configure cluster

- Set up access

- Review

- Service dashboard

6. Amazon Lambda DynamoDB Stream Trigger (java) : DynamoDBtoES




7. Develop AWS Lambda Java Project in Eclipse

- New Project : AWS Lambda Java Project


- New AWS Maven Project : awsLambdaDynamoDBStreamtoAmazonES

 : Class Name: LambdaFunctionHandler

 : Input Type : Dynamodb Event


- Check the items of DynamoDB when running pi4j


- Check the insert event message in the Cloud Watch Log 

 : public Integer handleRequest(DynamodbEvent event, Context context) {

   context.getLogger().log("Received event: " + event);

{ApproximateCreationDateTime: Mon Aug 13 12:07:00 UTC 2018,Keys: {id={S: 2018-08-13T12:07:12.024Z,}},NewImage: {bucket={S: rdiot-test,}, id={S: 2018-08-13T12:07:12.024Z,}, sip={S: 211.245.211.252,}, event={S: ObjectCreated:Put,}, value={S: {"name":"temperature","value":33.0},}, key={S: pi_dht11_2018813079.json,}},SequenceNumber: 187352800000000003101012958,SizeBytes: 175,StreamViewType: NEW_AND_OLD_IMAGES}



- Key Code
for (DynamodbStreamRecord record : event.getRecords()) {
            context.getLogger().log(record.getEventID());
            context.getLogger().log(record.getEventName());
            context.getLogger().log(record.getDynamodb().toString());
            switch (record.getEventName()) {

Serial MP3 Music Player Module for Arduino (YX5300) [B208]





https://www.youtube.com/watch?v=D9rsBf1b3CM


GitHub : https://github.com/rdiot/rdiot-b208


* Specs

The module is a kind of simple MP3 player device which is based on a high-quality MP3 audio chip---YX5300. It can support 8k Hz ~ 48k Hz sampling frequency MP3 and WAV file formats.

There is a TF card socket on board, so you can plug the micro SD card that stores audio files. MCU can control the MP3 playback state by sending commands to the module via UART port, such as

switch songs, change the volume and play mode and so on. You can also debug the module via USB

to UART module. It is compatible with Arduino / AVR / ARM / PIC.


Features:

1. Support sampling frequency (kHz): 8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48

2. High quality


3. Support file format: MP3 / WAV

4. Support Micro SD card, Micro SDHC Card

5. 30 class adjustable volume

6. UART TTL serial control playback mode, baud rate is 9600bps

7. Power supply can be 3.2 ~ 5.2VDC

8. Control logic interface can be 3.3V / 5V TTL

9. Compatible with Arduino UNO / Leonardo / Mega2560 / DUE

Crash Collision Sensor Detection Module [S230]





https://www.youtube.com/watch?v=1yeZcZQk-Y8


*GitHubhttps://github.com/rdiot/rdiot-s230.git


* Specs 

Wrobot Crash Sensor is arduino compatible and can be used for for robot collision detection, touch collision detection. 

It is based on the high sensitivity crash sensor. 

With the Arduino sensor expansion board, in combination, it can be very easy to achieve robot collision detection, touch collision detection. 


When touch, output low level ; when release, maintain a high level

Wrobot Crash Sensor pin definitions : (1) Output (2) Vcc (3) GND

Features :

1.Based on the high sensitivity crash sensor

2.Can be used for robot collision detection, touch collision detection

3.Type : Digital

4.Sensitivity : High

5.Power Supply : 5V

6.Pin Definitions : (1) Output (2) Vcc (3) GND

7.When touch, output low level ; when release, maintain a high level

8.Apply to a variety of platforms including Arduino/51/AVR/ARM


* Contents

- connect

OUT - D3

VCC - 5V

GND - GND

 

- Key Code

int ledPin = 13;                // choose the pin for the LED
int inputPin = 3;               // connect sensor to input pin 3
 
 
void setup() {
  Serial.begin(9600);           // Init the serial port
   
  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare Micro switch as input
}
 
void loop(){
  int val = digitalRead(inputPin);  // read input value
  if (val == HIGH) {                // check if the input is HIGH
    digitalWrite(ledPin, LOW);      // turn LED OFF
  } else {
    digitalWrite(ledPin, HIGH);     // turn LED ON
    Serial.println("Switch Pressed!");
  }
  delay(50);
