GalvYas is a smox(small box), it "senses" farm fields, from the crop to the harvest, and let us watch those "sensations" on our tablet, smartphone or web browser. We have a working prototype, and we hope to someday have this marvellous machine available on the market to the public as we're still a bunch of startin-up tech-farmer dreamers. Our next goals to this smox, go so far ahead, when we will control deeper with more senses such as "sight", "smell" and "hearing".
