Understand how sensor nodes collect and communicate information collected on the IoT. Then see how controllers make decisions based on the information gathered.
- [Instructor] Much of the innovation in…the Internet of Things relies on millions…of low-powered sensors that monitor processes,…take measurements, gather data,…and communicate to other devices…and data repositories.…A sensor has sensors, power,…processing capabilities, and onboard storage.…The node has wireless communication interfaces,…and often has location awareness…using a global satellite system…and a positioning algorithm.…
Multiple sensor nodes create an…interconnected networked infrastructure.…Each sensor typically has the capability…to collect and route data to a central…data repository for processing.…The final processing node gathers the data…so the devices can react.…Basic elements in a sensor network include sensor nodes.…These are wireless devices that have…low power requirements, so there's rarely…a need to change the battery.…
These collect and communicate information on the IoT.…Gateway sensory node.…These collect data from sensors…and make decisions based on the information gathered.…They may have the ability to make…

4/24/2017Lisa Bock kicks off the course with an overview of IoT, and the types of IoT devices designed to improve the quality of life in homes and businesses. Lisa covers different networks that range in size and purpose—LANS, WANS and PANS—and explains how businesses invest heavily in IoT in order to keep a competitive edge, going into IoT developments in automobiles, building automation, and the medical field. She then evaluates consumer devices, such as wearables and mobile devices. Plus, she discusses zero-configuration networking, service discovery, designing IoT security, and more.
