Atomic Data Labs

Health and Sensors

I am not a doctor just play one on the computer

Introduce the historical what they were doing with the data

The ultimate challenge

Potentially millions of devices: with different purposes *

*Devices can publish many times a second

Know where the devices are Alerts and monitoring in real time**

**Real time means real time not kinda real time

Analytics No expensive Greenfield project Treat people as individuals

Needed a standard device protocol

Examples: temp, gyroscope, lighting, footfalls, windows and door, sleep monitors AND mobile phones

  • Open Source
  • Hardware agnostic
  • Easy to get started
  • Bonus Points: Active community
non negociatiable, i did not want to be supporting a vendor product

MQTT

"Message Queuing Telemetry Transport"

M2M connectivity protocol

Open Sourced by IBM

Suitable for low bandwidth and low powered devices

Extremely lightweight

protocol had to be open we didn't want to be tied to a brand of

Example Usage

St Jude Medical uses MQTT with its heart pacemakers to send cardio and pacemaker data for their clinicians remotely monitoring at home patients. This is done to provide the patients a better quality of life and reduce the amount of patient travel for check-ups.

Publish and Subscribe Model

M2M (Machine to Machine) example

(require '[clojurewerkz.machine-head.client :as mh])

(def conn (mh/connect "tcp://mqtt.opensensors.io:1883" (mh/generate-id)))

(defn over-pollution [limit]
  "give me a limit and if pollution levels goes over that tell me about it"
   (mh/subscribe conn ["Pollution"]
                (fn [topic meta payload]
                  (let [pollution (Integer. (String. payload "UTF-8"))]
                   (if (> pollution limit)
                     (println
                      (format "Danger pollution level is currently at %s over the limit of %s" pollution limit)))))))

(mh/publish conn "Pollution" (str 100))

Build Alerts

Understand what is normal for each individual

  • Fall Detection
  • Time Series

Device data is not Interesting

unless enriched with context

Message Queues

RabbitMQ

Realiable Messaging Service

Analytics

Queries on distributed databases we know already

Real Time Analytics using Storm

Key Value Stores

Enrich the data to give it context

What happens when we scale to whole cities

Publish data for free when using an open data licence

Enable Developers to build services using technology they already know

You start finding devices everywhere

A Smart City?

Why Open?

The scale of the challenge is too big for any one of us to solve

Smart Assistive Environments

Offer a number of available services

Future Cities Hackathon

140 developers over a weekend

Challenge: "Make the lives of the people of the City of Westminster better" List of submissions

The Problem

“Sensor device > Data Provider > people > DB > people > ETL > people> CSV > public entity> people > ETL> IT Vendor> DW > people > CSV > Sharepoint > Dropbox > and… us !!!”

Data: Use it or lose it

Lessons Learned

  • Open by Default
  • Composable systems
  • KISS

Gall's Law

John Gall, Systemantics: How Systems Work and Especially How They Fail

"A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: A complex system designed from scratch never works and cannot be made to work. You have to start over, beginning with a working simple system."

Grand--er Ambitions

  • Open source software/hardware projects
  • Help the spread of knowledge about hardware potential to the mainstream
In his critique of systems theory.

Nice to haves

More Open Hardware

Multi purpose hardware

Interoperable Systems

Paraphrasing Sir Tim Berners-Lee

If you open your data people will use it in ways that you never expected

Thank you
