==Water Sensor (Grove 101020018) component==
The water sensor uses a 1M ohm pull-up resistor. The resistor will pull the sensor trace value high  until a drop of water shorts the sensor trace to the ground trace. You can use it with an analog input pin to detect the amount of water in contact between the grounded and sensor traces.
