The Plant Bot is an open-source, Internet-enabled plant monitor powered by the ESP32-C3 microcontroller and integrating a corrosion-resistant capacitive
They are saying the circuit (being capacitive) doesn’t have the electrolysis effects of the normal resistive circuit. That’s all. Look at the PCB; I work with these things – You HAVE to seal the edges with solder resist as well, to seal the system.
From the picture, the edges of the PCB are exposed
Yes, they’re using a capacitive sensor; but they haven’t manufactured it appropriately to negate moisture ingress from the sides, which will delaminate the PCB.
I can tell you already it’s garbage.
From the picture, the edges of the PCB are exposed, which means it’s going to corrode in the moist soil. Avoid.
Use a capacitive sensor, and make sure it’s one that’s fully encapsulated and sealed at the area where it enters the soil.
The first line states that it IS capacitive and corrosion resistant.

Maybe pay more attention to the words written.
