A simple node to check on your plants. It can check on 6 plants. It uses cheap capacitive sensors, which don't rust and are less affected by soil minerals. Optionally, the user can connect 6 warning LED's (or 6 solenoids to give each plant water). - Non-blocking - Low memory use, to allow encryption on an Arduino Nano.
