• Voltage : 5V LED lamp power light, the output signal.
• TTL level output, TTL output signal for low level effectively. Ability to drive about 100 ma, can be directly driven relay, buzzer, small fan, and so on.
• Sensitivity can be adjusted through the potentiometer
• No rain when the LED light output for the high level, rain, and the output level, the LED light.
• Raindrops board and control board are separated, convenient to wire leads.
• The raindrops plates of large area, more conducive to detect the rain.
• The board with a hole, convenient installation
• Control panel board size : 3x1.6mm
• Large area of rain test plate 5.4x4.0mm

Two methods of use :

• Connected to 5V power supply power lights, no water droplets on induction plate, the DO output for the high level, switch lights out, a drop of water drops, the DO output for the low level, switch indicator, Brush away the water droplets, return to again, the output high level...
• AO analog output, can be connected to the microcontroller AD mouth drops of rainfall in the above size.
• DO TTL digital output can also be connected microcontroller detecting whether it will rain.
