Description
This is a moisture sensor project based on the GardenBot project(https://gardenbot.org/howTo/soilMoisture/), it runs the current both forward and reverse. This allows to use a cheap two-probe soil moisture sensor with a less electrolysis.
This is my first PCB, so any suggestion or advice is very welcomed!
