thingiverse

To begin, print out two parts for your soil moisture sensor. Then, securely attach 50mm long, 3mm diameter nails to each part by soldering their wires. Next, insert these nails into the provided spacer and fasten the cover in place. Your sensor is now prepared for use. To monitor soil moisture levels, connect it to a preferred controller like an Arduino using a voltage flipping method; refer to Gardenbot's connection diagram for guidance.
