Float sensor inversed, how to change in code? [SOLVED]

[Sidney van der Stoep]

Goodmorning everybody,

I've got an question, my float sensors are inversed and due to the construction of the sensors it isn't an option the turn the float sensor arround. So I have to change it in code.

I've found the code below:

Code: Select all

void check_nivel() // Verifica o nível do reef e fish only.
{
  if ((myAnalogRead(sensor5) > 400) || (myAnalogRead(sensor6) > 400) || ((myAnalogRead(sensor2) < 400) && (bitRead(tpa_status, 1) == false)))
  {
    nivel_status1 = true; // Sinaliza nivel baixo em um dos aquários ou sump
  }
  else
  {
    nivel_status1 = false; // Sinaliza nível normal dos aquários e sump
  }

To inverse the signaling do I have to swap the nivel_status1 values true and false?


I was also wondering if there's a failsave mechanism if the float sensor in the reef is broken? I'm a little bit afraid that if the sensor is stuck the ATO will overflow the aquarium. Is it possible to set a max. runtime or another failsave option?

Regards!

Hi!

Welcome Sidney!

Not, change the logic of < and >.

Not, in my system the level sensor is in redundancy with float valve. If the float valve fail the system will turn off a solenoid to prevent fill the thank with fresh water.

Best regards.
