Note:
Rain drop board need to be used with module.The module can output signal(DO,AO).
Instruction:
When VCC input is DC 5V, indicator is ON. If rain drops on sensor panel, DO outputs on low level and indicator keeps ON. Else no rain drops, DO outputs on high level and indicator turns OFF.
If remove the water, then the DO LED will recover to high electrical level...
