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.
