These tiny, lightweight gadgets could mean huge savings for farmers

"Farmers have a very good eye. They can look at their crop if they've been farming for a long time and say, 'My crop needs water, I can tell,'" says Richard Stoner, founder of the biotech and agriculture company, AgriHouse.

With funding from the National Science Foundation (NSF), AgriHouse has developed a leaf sensor that is enabling plants to do just that.
