Overview
This rain sensor and water detection sensor is used to detect water leak, water level or rains. This is obtained by having a series of parallel wires exposed traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.
AO analog output can be connected to the microcontroller detects AD mouth drops of rain in the above size.
DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain .
The analog signal output can be read directly to Arduino
