The Internet of Things - continued
“IoT describes a system where items in the physical world, and sensors
within or attached to these items, are connected to the Internet via
wireless and wired Internet connections.”
IoT is very broad, not contained to a single technology.
It does not matter what you use, it is important how you use it.
Internet is the keyword in the internet of things. Communication is the most
important aspect of it al.
Collecting, analysing but above all communicating data is what IoT is
Internet of Things can aid in optimizing workflows, providing better
information gathering, lower costs, etc...
Business cases can include:
▪ Geospatial tracking (where does a worker go/check in)
▪ Measurements (supply/factory lines/…)
▪ Combining multiple inputs (data acquisition)
Business case: ISS
▪ Track arrival and departure of workers at clients
▪ Employees must not be able to cheat/damage/...
▪ Not all customers allow for devices to be installed
⇒ Multi-tier solution
⇒ Still in progress
Tracker device that can be installed in cars (business) and at customers.
TODO: What if no business car or customer does not allow devices...
A quick terminology overview!
RAM = Random Access Memory (operational memory)
ROM = Read Only Memory (stores the program-s)
EEPROM = Electrically erasable programmable - ROM
IO = Input & Output
GPIO = General purpose IO (pin in and out)
CPU = Central Processing Unit
=> Architecture => X86/X86_64/ARM/PPC/...
You will see these terms in a lot of the IoT devices.
The world of the IoT is built upon varying technologies, below are some
▪ BlueTooth Low Energy
▪ Distributed computing
▪ Mesh networks
▪ Analog & digital electronics
In the following slides we will give a short overview of the most current
devices used for IoT
▪ Raspberry Pi
▪ Intel Edison
▪ Particle.io (Spark Core, Photon & Electron)
Devices - Raspberry Pi
▪ Multiple use cases, mostly for digital signage or as mediaplayer
▪ Storage: SD card (OS) or external HDD (USB)
▪ Different models (A/B/B+/2)
⇒ Arduino on steroids. Has a much better cpu, but mainly the same IO
pins (plus extra usb/sd card)
Devices - Particle.io
Spark Core, Photon & Electron
▪ From prototyping to full rollout
▪ Ready-to-go device: hardware & software already supplied
▪ Connects to cloud
▪ Manage and control devices using a REST api
▪ Vendor lock-in
Devices - Pinoccio
▪ Language: ScoutScript, extendable with custom C/C++
▪ Storage: 256KB flash
▪ Ready-to-go device
▪ Manage devices using the cloud infrastructure
▪ Program unit through webapp or arduino IDE
Devices - Beaglebone Black
▪ 512MB DDR3 RAM
▪ 4GB 8-bit eMMC on-board flash storage
▪ 3D graphics accelerator
▪ NEON floating-point accelerator
▪ 2x PRU 32-bit microcontrollers
⇒ Was a Rbpi “clone” now obsolete with the Rbpi2
⇒ Easier to setup and use then the Rbpi
In the next session
We drill down on the Raspberry pi:
▪ Setting it up with an OS
▪ Configuring it for development
▪ Java on the Raspberry pi
▪ Using the GPIO
Other things for the next session:
▪ Update on the ISS business case
▪ Introduction and invitation to project Trafficker.
