This presentation discusses the concept of the Internet of Things (IoT) and why it has become popular. The IoT represents a network of physical objects embedded with sensors, software, and other technologies that connect and exchange data. It allows companies to make better business decisions using collected data and analytics. Key factors driving the growth of IoT include improvements in hardware, software, networking, and cloud computing technologies that have made it more affordable and scalable. Safety is the top priority in any IoT system to ensure devices operate safely and securely.

Editor's Notes
- Demo showed a Raspberry Pi running a Java application. The application reads the room temperature and flashes an LED. On the screen, I show a website (AWS) that shows the current temperature and the state of the LED. It also shows a histogram of the temperature. Then I show it on a tablet. I pass the tablet around to the class. To make it interesting, I put a cold soda can on the thermocouple causing an alarm to ring on the tablet. Almost lost my tablet
- Examples: Money Get a Job in it Invest and save in long run (utilities, government) Will be ubiquitous Privacy – if you aren’t paying for something, you are the product Sell more shoes (Nike, Underarmor) Sell healthcare info for advertising Insurance risks Safety Start/stop equipment (push PE here) Hacking Legal (tracks where you are)
- Zone Controller manages a section of a machine or a complete machine Machine Controllers manage zones and report data up to big server Industrial busses because of electrical noise and real time requirements (especially deterministic data)
