parrot is already doing this but only sell a camera and color sensor. they sell drones too. parrot is the original person to think of this. here's the link to their website ---> parrot.com
We actually don't sell drones. We use drones along with custom tractor-mounted sensors and our software. With this combination we directly correlate field performance at specific growth stages to yield. We're allowing produce growers to perform controlled experiments on their fields to know exactly where the good crop comes from and why. Sensors by Parrot are awesome and can be integrated into this work flow.
