Let’s do some IoT stuff… with an Arduino board and Azure Stream Analytics Internet of Things

Merci à nos sponsors…

Session Logistics Speaker : Florian Eiden SQL Server MVP/ Data English or French? Recorded, but you are here, so you are the important ones! Content : 20% slide deck, 80% demo Some code : C, Python; on Linux and Mac OS… But Azure and Power BI! Yes you can leave now, no offence taken ;) Cellenza 156, bd Haussmann Paris, France

Internet of Things What’s the point? International Business Times : Connected CattleConnected Cattle By David GilbertDavid Gilbert

Internet of Things What’s the point? 4 different scenarios (Clemens Vasters – MSDN)Clemens Vasters – MSDN Telemetry : my device streams data from sensors Inquiries : my device asks for stuff for its process to complete Commands : I order my device to do something Notifications : I notify my device so that it can do stuff if it wants to

Arduino Yun = Base + Linux + Wifi & Ethernet Base System : Circuit board + pseudo C Yun Linux : Linux… so Python in my case :) (Because Azure SDK in Python!) Pseudo C Python

Arduino : C Let’s go have a look ;)

Arduino : Python Let’s go have a look ;) First on the Mac Then on the Arduino by ssh Then see

So now that we have data coming in, lets play with it!

14 (Stream Analytics) Data at Rest SELECT count(*) FROM ParkingLot WHERE type = 'Auto' AND color = 'Red' Question “How many red cars are in the parking lot?” Answering with a relational database Walk out to the parking lot Count vehicles that are: Red, Car

15 (Stream Analytics) Data in Motion Different Question “How many red cars have passed exit 18A on A-10 in the last hour?” Answering with a relational database Pull over, park all vehicles in a lot, keep them there for an hour Count vehicles in the lot Not a great solution…

16 Stream Analytics SELECT count(*) FROM A-10 WHERE Type = ‘Car’ and Color = ‘Red’ GROUP BY TumblingWindow(hour, 1) Different Question “How many red cars have passed exit 18A on A-10 in the last hour?”
