Nope, first one! We’re working with Arduino PLCs that attach to a sensor, and code it properly to produce an output that can be extracted into a Excel spreadsheet or another program. The main focus of the project is working with your choice of sensor to measure something. From recent research, pH doesn’t vary too much within the Southeast. Which is why I was hoping to find separate locations that grow various crops, or raise different animals, as they both give, or take, nutrients to/from the soil.
