Gallery: 10 ways technology is changing disaster response

​1. Internet-connected sensors

Harris County, home to Houston, was hit hard by hurricane Harvey. Despite being battered, Houston managed to stave off the worst, and internet-connected sensors may be partially to thank.

The Harris County Flood Warning System (FWS) gave government officials a real-time look at which sections of Houston were at greatest risk of flooding, thanks to 142 gauge stations. Each station is equipped with rainfall sensors and water level sensors that monitor the state of Houston's creeks and bayous.

This internet of things system may well have saved countless lives.
