The idea is simple enough. The sensors monitor temperature and humidity, along with the volatile compounds that signal how moist a farmer's grain is. Since this is 2017, those farmers will be able to monitor that key data from their smartphones, and that sort of easy access should help them figure out the ideal time to sell and ship their crop.

But there's more to this idea than just helping the world's farmers demand the best possible prices. Amber co-founder Lucas Frye also believes that some serious long-term good could be possible if the company could work with farmers in countries where grain spoilage has been a pressing issue. Frye, a competent, low-key pitchman, says the startup's vision is on some level about protecting our food supply. That said, smart moisture management won't be able to fix every grain spoilage problem around the world. Consider India: Spoilage and grain rot are a recurring problem there, but that's thanks in large part to logistical issues like finding places to actually store those huge crop hauls.

For now, though, global problems are taking a back seat while Amber makes sure everything works the way it's supposed to. There's no firm word on pricing yet, but that's to be expected: After finalizing some design elements and striking some deals, the startup's leaders are gearing up for its first set of field trials in early 2017.
