Chungnam National University 4 Computer Science and Engineering Database System Laboratory ioBridge, Inc. Labs[2/4] ‒ Tide Alerts
Tide Alerts is a project developed by ioBridge to monitor and report tide levels in real-time using low-cost, battery-powered sensors connected to ioBridge cloud services
■ http://tidealerts.com/
Users can see current and historical charts, contribute their own data, and set customizable email notifications so you know exactly when to get your boat back to the dock without getting stuck in low water levels
Chungnam National University 5 Computer Science and Engineering Database System Laboratory Ockway Bay Tide Levels
Chungnam National University 6 Computer Science and Engineering Database System Laboratory ioBridge, Inc. Labs[3/4] - ioAuth
The Internet of Things will not be complete without a comprehensive security model
ioAuth is a set of open standards that involve how devices and systems authenticate to web services
We are used to the model of signing into a website or authenticating with an API
Devices require the same architecture
■ ioAuth is OAuth for "things" (specification coming soon)
Chungnam National University 7 Computer Science and Engineering Database System Laboratory ioBridge, Inc. Labs[4/4] - ThingSpeak
ThingSpeak is an open source "Internet of Things" platform for storing and retrieving data using HTTP commands
ThingSpeak also includes a suite of applications designed for making "social things“
This cloud service is open to anyone and can be used with many devices, robots, and things
Chungnam National University 8 Computer Science and Engineering Database System Laboratory ThingSpeak
ioBridge, Inc. releases ThingSpeak (April 18, 2011)
■ The first open source solution for "Internet of Things" products and services – Much like WordPress allows people to create blogs easily
■ ThingSpeak (http://www.thingspeak.com) allows developers to interact with devices using standard Web technologies
■ ThingSpeak can be run via its free hosted service or on personal servers
Chungnam National University 9 Computer Science and Engineering Database System Laboratory ThingSpeak Goals
"Our goal is to take some of the mystery out of connecting devices to the Web," said Hans Scharler, President of Software at ioBridge.
Everyone is discussing the Web of Things as if it's in the future, but cell phones are the perfect blend of things, social interaction, and the Web
■ I think of mobile devices as sensor platforms and gateways to Web services
Chungnam National University 10 Computer Science and Engineering Database System Laboratory Internet of Things Devices
Range from microcontrollers to computers Need to be able to push data to Web Services They might push “a lot” of data Open Data + Thing Data = Web of Things
ThingSpeak App Platform
Chungnam National University 11 Computer Science and Engineering Database System Laboratory ThingSpeak Features [1/4]
Features of the ThingSpeak platform include data logging, data processing, data distribution, location-based services, status updates, social network integration, apps, and plugins
All-purpose Data Storage and Retrieval
■ Data Storage – You use ThingSpeak to Send and Receive "data" via simple HTTP requests, much like going to a web page and filling out a form – Data can be from anything - Blood Sugar Levels measured by a glucose meter, Server Usage and Uptime reported by servers, or Location Info from a mobile phone – Once the data is in ThingSpeak, you can build applications that retrieve the data, use the data for process decision making, and reporting
■ Data Retrieval – Data is stored in a ThingSpeak Channel – Each channel allows you to store up to 8 fields of data up to 255 alphanumeric characters
Chungnam National University 12 Computer Science and Engineering Database System Laboratory ThingSpeak Features [2/4]
Data Importing
■ Do you already have a bunch of data collected from data acquisition devices, server logs, or sensors?
■ Then you can use the ThingSpeak Importer to bring in your existing data and leverage the ThingSpeak API and Charts to share with and connect to applications instantly.
Dynamic Charting
■ When you need to visualize your data, ThingSpeak has dynamic charts and an API to make customizations
■ The charts are perfect for displaying sensor data over time and finding some meaning behind the data
Data Processing
■ When pulling data out of ThingSpeak, you can process the data to get it ready for your application
■ You can also filter the data by setting minimum and maximum value thresholds
■ Processing options include time scaling, summing, averaging, and median
Chungnam National University 13 Computer Science and Engineering Database System Laboratory ThingSpeak Features [3/4]
Integration with Twitter
■ Often enough you will find times where you want to share significant data across social networks like Twitter
■ You can have your garage door Tweet, "You left your garage door open" or have your house, say "Today's Power Use was 6150 watts.“
■ The ThingSpeak API has Twitter baked in, so you can send status updates to Twitter along with storing your data in a ThingSpeak Channel at the same time
Fully Localized
■ ThingSpeak supports over 40 time zones and time offsets for locations that support Day Light Savings
■ When charts and data are presented to users, we format times and dates using the viewer's time zone
Chungnam National University 14 Computer Science and Engineering Database System Laboratory ThingSpeak Features [4/4]
Privacy Options for Open Data
■ You can choose to make your data public or private
■ Over 95% of ThingSpeak Channels are private meaning that the data is not publicly accessible without API keys and user authentication
■ You can control who has access to your data and build applications that are open to those that you choose
Open Source API and Web App
■ https://github.com/iobridge/ThingSpeak
Chungnam National University 15 Computer Science and Engineering Database System Laboratory ThingSpeak Apps
Integrated Web Apps
■ ThingTweet – Link your Twitter account to ThingSpeak and send Twitter messages using our simple API
■ ThingHTTP – Low-level access to high-level web resources – Create custom POSTs or GETs to other Web Services and retrieve the data
■ TweetControl – Listen to commands from Twitter and then perform an action
■ React – Perform actions when conditions are met by your data in your channels
Chungnam National University 16 Computer Science and Engineering Database System Laboratory ThingHTTP - Google Weather Tutorial
Parse Weather Data from Google Weather with ThingHTTP
■ ThingHTTP can be used by a microcontroller to send HTTP requests and then parse the response
■ This is useful so you do not have to take code space, which is limited, away from the microcontroller
■ This tutorial shows you how to create a ThingHTTP request to Google Weather and parse out just the current temperature from the XML response
Chungnam National University 17 Computer Science and Engineering Database System Laboratory Plugins
Display a Google Gauge Visualization using ThingSpeak Plugins
■ This tutorial shows you how to use a Google Visualization inside of ThingSpeak Plugins
■ We will be the Google Gauge visualization to display the last value of a ThingSpeak channel
■ We will be using jQuery to get and parse JSON from the feed
■ The Google Gauge also auto updates with the latest value using JSONP
Chungnam National University 18 Computer Science and Engineering Database System Laboratory Devices
The Devices tab in ThingSpeak is a place to store information about your devices such as an Arduino, Netduino, mBed, Spinneret, or an ioBridge device
■ The information you can store is name, model, public IP address, and public port number
■ The IP and port number will be used for a future dynamic DNS app and are optional
Chungnam National University 19 Computer Science and Engineering Database System Laboratory Featured Channels
Chungnam National University 20 Computer Science and Engineering Database System Laboratory my_house Channel
Chungnam National University 21 Computer Science and Engineering Database System Laboratory Social Sensor Network
The first commercial application to be built on ThingSpeak is the Social Sensor Network
■ http://www.socialsensornetwork.com
■ This application makes use of people as sensors by allowing users to report and share any data on a social channel via a web browser
■ The data is processed and presented in a meaningful way
■ All of the data is open and available so other developers can make use of it
Web and mobile app used to collect data that sensors can not sense
■ “It’s hot in here” / “Lots of ladies here”
