Monitor changes in soil moisture with this resistive probe board. Two exposed pads respond to conductivity changes in the surrounding material: wetter soil lowers resistance and raises the analog signal. An onboard ATtiny85 provides an I2C gateway through the Qwiic connector, supporting integration with a compatible development board.
