U.S. Rep. Rob Woodall, R-Ga., visited Discovery High School on Friday morning for a presentation on the Internet of Things technology developed in Georgia to keep schoolchildren safer during arrival and dismissal times.

Gwinnett County and the state of Georgia have pioneered large-scale deployment of the technology for “smart” school beacons. The technology connects school zone beacons — those flashing signs that are intended to slow drivers down as they pass by a school.
