Soil Sensor

Documentation for the FarmBot Genesis soil sensor

This single 3D printable component magnetically mounts onto FarmBot's UTM like any other tool. It works by driving the tool vertically into the soil so that the soil properties can be accurately read.

Step 1: Install the magnets

Install only the magnets using the instructions in the basic tool hardware reference guide.

Step 2: Install the soil sensor PCB

Attach the soil sensor PCB to the soil sensor using two M3 x 12mm screws and M3 locknuts. The sensor should be on the front side of the base's mounting tabs. The heads of the screws should be on the PCB's front side while the locknuts should be on the mounting tabs' back side. Do not over tighten the screws as this could damage the circuit board.

Step 3: Install the electronic screws

Use the 2mm hex driver and 5.5mm box wrench to secure the following ring terminals to the soil sensor with M3 x 12mm screws and M3 locknuts. The screw heads should be on the same side as the magnets.
