Homemade Arduino Hardware and Android App Software Development for Small Farms

What started as a simple test stand for my planter's finger seed meters has grown into a set of key systems for precision farming. The test stand grew into a basic planter monitor system that I have been enhancing each year. I started the outFARMING website to pay it forward by offering low cost products for small farmers. When I upgraded my planter to a 12 row it came with liquid fertilizer tanks that had not been installed. That lead to developing a monitor for fertilizer. As my needs grow, I just start the next DIY project.
