“I buy parsley in pot, and most of day, soil were dry. So I decide to make this project, about sensing moisture of soil in pot with parsley, to check, when I need pour soil with water.
I think, this sensor (Capacitive moisture sensor v1.2) is good because:
1. has waterproof electrodes, so you don’t worry about corrosion.
2. is cheap -> 1,5 - 2 $”
