Only 1 sensor osmosi

[Simone Sandonati]

I would make topping up system of evaporated water with the use of only one float in sump
on temporary protection after 10 seconds if the sensor has not arrived to the off position you must stop the pump and trigger an alarm at the same time if the sesore returns off the first of 10 seconds must always stop the pump but without alarm

I did so but I do not work the time of 10 seconds

Code: Select all

const byte sensorerabbocco = 49;
const byte pinrabbocco = 47;
boolean allarme_rabbocco = false;
unsigned long temporabbocco = 0;



tab setup

Code: Select all

pinMode(sensorerabbocco, INPUT_PULLUP);
pinMode(pinrabbocco, OUTPUT);


tab loop

Code: Select all

if (digitalRead (sensorerabbocco) == LOW)

{
   if (allarme_rabbocco == false)
    {
      digitalWrite(pinrabbocco, HIGH);
     

            if (millis() - temporabbocco > 10000)
   
        {
          digitalWrite(pinrabbocco, LOW);
          allarme_rabbocco = true;
          temporabbocco = millis();
        }
           
    }
}
else
 {
  digitalWrite(pinrabbocco, LOW);
  temporabbocco = millis();
 }

Hi!

Try this:

Code: Select all

if (digitalRead(sensorerabbocco) == LOW)
{
  if (allarme_rabbocco == false)
  {
    if (digitalRead(pinrabbocco) == LOW)
    {
      temporabbocco = millis();
    }
    digitalWrite(pinrabbocco, HIGH);
  }
}
else
{
  digitalWrite(pinrabbocco, LOW);
  allarme_rabbocco = false;
}

if (((millis() - temporabbocco) > 10000) && (digitalRead(pinrabbocco) == HIGH))
{
  digitalWrite(pinrabbocco, LOW);
  allarme_rabbocco = true;
}


Best regards.
