Building Enterprise IoT Projects Iteratively - Vui Nguyen

The document discusses how to build enterprise IoT projects iteratively using an example water pipe monitoring system. It describes how the system started as a proof of concept at a hackathon using basic sensors (Phase 1) and was iteratively improved by adding a web interface (Phase 2) and scaling to monitor multiple pipes (Phase 3). The key lessons are to start small, prove concepts work, and scale features over time while maintaining scope and deadlines. Iterative development allows projects to grow from initial prototypes to full enterprise solutions.

- 2. Talk Overview How to start doing IoT How to grow Use Case Example: Save the Water Pipes Very hackathon-centric, but some of the principles can be applied to commercial applications as well Always ask: who is my customer and what is the immediate need? Where and when it’s possible: how can I design this so there’s room to grow while still meeting the immediate need and deadline? Won’t go too deep technically, describe the process of improvement
- 3. In the Beginning April 2016, the “Blue Team” enters the Intel IoT Roadshow in Denver We win first place with our freezing water pipe detection and prevention system Detects when water in a pipe is about to freeze When temp gets into “red” zone, stepper motor opens a valve to release water When temp gets into “yellow” or safe zone, stepper motor closes the valve
- 5. Technologies Used Intel Edison board Intel XDK: IoT Edition Javascript-based IDE to build IoT applications Intel libraries: Javascript wrappedArduino Grove shield and Grove sensors
- 6. What Was Missing? Notice there is no pipe, water temp sensor is placed directly into bucket to simulate “freezing water temp in pipe” Water temp sensor is taken out of the bucket and placed between our fingers to “warm up the water temperature” Another trick: water temp sensor measures voltage, not temperature. We had to adjust our algorithms to get the results that we want
- 7. What Was Missing? (cont.) All sensor data displayed to console and LCD There is no website, mobile app, any software other than JavaScript-wrappedArduino code (Intel hardware libraries) Used sample sensor code within the IDE to get started
- 8. Why Did We Win? Strength and simplicity of our idea we focused on 1 problem and demonstrated its solution well Strong hardware and sensor demo We told a compelling story during our presentation We tried not to do too much at once - only had 2 days to work on project start to finish & first time working with Edison board and Intel IDE and technologies The point of hackathons is to show a concept is possible, NOT to build a market-ready product. We saw some teams fail because they lose sight of this
- 9. China US Young Maker Competition Fresh from our success at the Roadshow, we entered the China-US Young Maker Competition on hackster.io, also sponsored by Intel A couple of weeks after the Roadshow, we got back to work We only had a handful of weekends to work together as a team Submission deadline: mid-June 2016
- 11. What Was Added Used an Intel sample application to get started: https://software.intel.com/en-us/creating-an-application-to- communicate-using-web-sockets Challenge: how to get the data “out” from the IDE console and into a useful application Asked: what did we want our “useful application” to do? Local web server hosted on Intel Edison board used to communicate between sensors and display results on website

- 13. How we worked together Version Control: Git and Bitbucket Project Management: Trello Schedule in person team meetings and used communication tools as needed: Hipchat I filled the role of software lead and architect Selected and largely modified the Intel sample application for the foundation of our project As team lead, ensured that we completed our project in time for submission by the deadline
- 14. Selected To Go To China Mid-August 2016, the “Blue Team” went to Beijing China to compete in final rounds of competition
- 15. Project Enhancements Simulate monitoring water pipes for multi-unit system instead of single unit Solenoids replace stepper motors to power valves Relay Shield added to power multiple solenoid valves
- 16. Project Enhancements Website has additional page to show status of all units in real time, plus existing page to show status of single unit in real time Requires refactoring of JavaScript code in back end (used JS objects)
- 17. Competition Results Successful in implementing improvements to system Placed 11th out of 64 teams overall Great experience! To learn more: https://sunfishempire.wordpress.com/2016/08/27/ save-the-water-pipes-project-wins-excellence- award-in-iot-china-contest/
- 18. Conclusions We didn’t get to where we are today overnight, we did it in steps. You should too! Phase 1: Start with controlling sensors and displaying sensor data to console Phase 2: Use sample application to start building real software application that displays data outside of IDE Phase 3: Refactor code as needed to scale system
- 19. Conclusions Part II DO Start Small, and add one feature at a time DON’T Think you must begin with an Enterprise-level IoT system right off the bat DO Use version control, project management, etc., as soon as feasible DON’T Stay in “Hack-a-Thon Mode” forever! DO Keep project requirements and scope in mind DON’T Spend time you don’t have on features you don’t need
