Great question. What separates Sprout from the others is definitely the cost. With sensors priced at $15 ea, our goal is to make them as simple and robust as possible. We are finding that a lot the current sensors out there have reliability issues and are very expensive. We're not trying to do anything too fancy by adding functionality that you won’t need, like integrating a large detailed plant database or taking measurements of soil pH levels. The sensors will stick to the most important question: does your plant need to be watered or not.
