Have power indicator, output signal LED indicator
TTL-level output, TTL output valid signal is low, drive capacity at 100mA, can directly drive relays, buzzer, a small fan, and so on
Sensitivity adjustable via potentiometer
The output is high LED light up when no rain, and vice verse
Raindrops board and the control panel is separate, convenient line leads
A large area of raindrops board, more conducive to rain detected
Board with positioning holes to facilitate installation
Control panel board size: 3x1.6mm
The raindrop detection plate large area 5.4x4.0mm

Connected to 5V power supply power lights, induction board no water droplets DO output is high, the switch indicator lights off, dropping on a drop of water, DO output is low, the switch indicator lights on
Brush off the the above water droplets, has returned to output to high state.
AO analog output can be connected to the MCU AD port to detect the size of the drops in the above rainfall.
