A light switch is just a light switch—until it gets smart. Connecting that switch to the internet or a private network may let you dim the lights from an app on your phone or track how much electricity you’re using, improving its capabilities and making your life that much easier. There are more than 30.7 billion digitally connected items like these within a realm known as the Internet of Things (IoT), and the industry is growing every day thanks to the skills of trained professionals.
What is the Internet of Things?
The Internet of Things connects digital data to the physical world. Through this network, items like fitness trackers and alarm systems use embedded sensors to exchange information with each other. Because of the IoT, your FitBit can track and store information about your health in a profile, and your doorbell alarm can keep surveillance video in the cloud. Devices within the IoT are often called “smart,” like smart locks that you can engage with the tap of a button in an app.
In addition to these daily applications, IoT devices have been designed to meet specific industrial needs. These include pressure sensors on oil and gas pipelines that allow for remote monitoring, moisture sensors that track water levels, and even drone technology that provides information for data-based decision making.
“The IoT is really about providing solutions to problems,” says Peter O’Reilly, program director for Northeastern’s Master of Science in Cyber-Physical Systems program. “These can be cost-effective solutions, or solutions that are better or more efficient.”
Careers for professionals designing these solutions are expected to grow as the Internet of Things continues to expand, O’Reilly says. Explore some of the top careers defining the IoT industry below.
