‘Thirsty Crop’ Sensors Save Water

A clip-on sensor the size of a fly’s wing could save farmers thousands — if not millions — of dollars a year in irrigation costs.

The sensor works with a wireless network to alert the farmer when crops need water or even start up irrigation systems automatically.

“We’re talking about saving 30 to 40 percent of water used,” said the technology’s inventor, Hans Seelig, a research associate at the University of Colorado at Boulder’s BioServe Space Technologies Center. “If you have an irrigation system that applies water in certain sectors, you could be even more efficient,” he said.

It sure seems like this could have an even broader impact given the amount of suffering due to the lack of water and looming specter of water  wars.
