[ baby description
voltage: 5V
power indicator, output signal LED indicator.
TTL level output, TTL output valid signal is low driving capacity of around
100MA, can directly drive a relay, buzzer, small fan, and so on.
Sensitivity can be adjusted via a potentiometer
no rain when the LED is lit the output is high, raindrop up, ground level
output, LED lights.
Raindrops board and control board are separate, easy to wire leads.
A large area of rain board, is more conducive to detected rain.
Board with positioning holes to facilitate installation of
the control panel board size: 3 * 1.6 MM
large raindrop detection plate 5.4 * 4.0 MM

Two use
when connected to the 5V power supply lights, no water induction plate, DO
output is high, switch lights off, dripping a drop of water, DO output is low,
switch lights,
brush the top of the water droplets , has returned to output high state. . . .
AO analog output can be connected to the microcontroller AD port to detect drops
in the above rainfall size.
DO TTL digital outputs can also be connected to the microcontroller to detect
whether there is rain.
