Shill time! This is a tiny leak detector pcb I designed. Works great with ESPHome (especially the SEEED Xiao ESP32-C3) or Arduino/STM32. Almost no power draw when dry, so it will be great for battery powered circuits.
FYI: You must use a RTC pin for wake from deep sleep, so the direct edge to edge mount won't work for this, as GPIO10 on the Xiao ESP32-C3 is not an RTC pin.
