In California the big new use for "connecting devices and data" is in agriculture, where 80% of water use by humans takes place. In the midst of a drought crisis, they need all the help they can get.
Farmer Richard Martinez "has to figure out where he can cut back on water just enough before it starts killing off his crops." That's tricky to do, so he has sensors for soil moisture (plus oxygen, humidity, etc) which can help him save 20-30% of his water usage by knowing exactly when and where to use his precious allotment of water.
