Features:Voltage: 5V
Power indicator light, the output signal LED indicating lamp.
TTL level output, TTL output signal for low level drive capacity of around 100MA, can directly drive the relay, a buzzer, a small fan, etc..
Sensitivity adjustment via potentiometer
No rain when the LED light output is high, the output level, go up, LED bright.
The board and the control board is separate, convenient wire.
A large area of the board, more conducive to detect the rain.
The board is equipped with a positioning hole to facilitate installation
Control panel board size: 3*1.6 MM
A large area of raindrop detection board 5.4*4.0 MM
Connect cable: 200MM
Code test pour l'entrée analogique :
int sensorPin = A0; // select the input pin for the potentiometer 0/1023
int sensorValue = 0; // variable to store the value coming from the sensor
int oldValue = 0;
int sensorDelay=100;
// Seuil en dessous duquel regarder l'évolution
int seuil = 1000;
void setup() {
Serial.begin( 115200 );
}
void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
if ( sensorValue < seuil )
{
// si la valeur a changé de 1 on n'en tient pas compte, il y a trop de fluctuation sur la ligne pour que ce soit important
if ( abs( oldValue - sensorValue ) > 1 )
{
Serial.print("D");
Serial.println(sensorValue);
}
}
delay(sensorDelay);
oldValue = sensorValue;
