IoT: An introduction
2 likes2,168 views
This document provides an introduction to IoT including: defining IoT as connecting physical items to the internet via sensors to collect and communicate data; discussing how IoT can benefit businesses through optimizing workflows and lowering costs; and describing common IoT devices and technologies like Arduino, Raspberry Pi, Intel Edison, Bluetooth LE, WiFi and distributed computing networks. The next session will focus on setting up the Raspberry Pi with an OS, using it for development, running Java programs, and controlling GPIO pins.
IoT: An introduction
- 1. 1 IoT - An introduction CC IoT Tim Ysewyn Frederick Bousson Kevin Van den Abeele
- 2. 2 Agenda In today's session: ▪ What is IoT ▪ How can IoT benefit the business ▪ Devices & technologies ▪ Examples ▪ Q&A
- 3. 3 Can’t keep up? Don’t understand something?
- 4. 4 The Internet of Things
- 5. 5 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.” - Cisco 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 about.
- 7. 7 Big business 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)
- 8. 8 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...
- 10. 10 Technologies 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.
- 11. 11 Technologies The world of the IoT is built upon varying technologies, below are some examples: ▪ BlueTooth Low Energy ▪ WiFi ▪ RF ▪ Distributed computing ▪ Mesh networks ▪ Java / javascript / .net / rails / … / C++ / C / … ▪ Analog & digital electronics
- 12. 12 Devices
- 13. 13 Devices In the following slides we will give a short overview of the most current devices used for IoT ▪ Arduino ▪ Raspberry Pi ▪ Intel Edison ▪ Tessel.io ▪ Particle.io (Spark Core, Photon & Electron) ▪ Pinoccio ▪ BeagleBone
- 15. 15 Devices - Arduino Arduino Uno: ▪ Prototyping ▪ Language: Arduino (based on C/C++) ▪ Storage: 32KB flash ▪ Different models (Uno, Due, Mini, Nano, …) ⇒ Mainly used for electronic projects that don’t require a strong cpu.
- 16. 16 Devices - Raspberry Pi
- 17. 17 Devices - Raspberry Pi ▪ Multiple use cases, mostly for digital signage or as mediaplayer ▪ Language: Java, Javascript, PHP, Ruby, … ▪ 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)
- 18. 18 Devices - Intel Edison
- 19. 19 Devices - Intel Edison ▪ Prototyping ▪ Language: C/C++, Arduino Sketch, Javascript, Python ▪ Storage: 4GB onboard ▪ Integrated WiFi (802.11 a/b/g/n @ 2.4 & 5GHz) ▪ Integrated BLE ⇒ More “high” power solution when compared to Arduino/Rbpi
- 21. 21 Devices - Tessel.io ▪ Prototyping ▪ Language: Javascript, Python, Rust ▪ Storage: 32MB onboard ▪ Integrated WiFi (802.11 b/g/n @ 2.4 & 5GHz)
- 23. 23 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
- 25. 25 Devices - Pinoccio Pinoccio ▪ Prototyping ▪ 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
- 26. 26 Devices - Beaglebone Black
- 27. 27 Devices - Beaglebone Black 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
- 28. 28 In the next session
- 29. 29 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.
