The Plant Bot is an open-source, Internet-enabled plant monitor powered by the ESP32-C3 microcontroller and integrating a corrosion-resistant capacitive
Love the idea, but capacitative sensors like this do degrade somewhat quickly. If you bump them, your calibration curve is no longer valid. Putting all of your electronics a centimeter from the soil, which will also be watered is also a mistake.
An esp32 dev board, a motor board and an unpluggable replaceable sensor makes so much more sense from a practical standpoint.
