Re: ph meter using pic 16f877 pls help on coding
the motor B will start pump out in both condition(ph>7&ph<7) so only ph 7 stays.
Do i need a reset button to repeat the process.
Re: ph meter using pic 16f877 pls help on coding
this is my schematic
- - - Updated - - -
i have two motors,
motor a= inlet(c5)
motor b=outlet(c6)
motor a will pump in water until reach the high level then ph sensor check the ph value if the value is less or higher than 7 motor b will pump...
Re: ph meter using pic 16f877 pls help on coding
i am very sorry totally forgot about the other motor,
actually there are 2 motors.
Motor A for inlet and motor B for outlet.
the process starts when motor A pump in water then stop when the water reach high level, then ph sensor check the value...
Re: ph meter using pic 16f877 pls help on coding
so if i set up sensor(water level) on portD then the motor will be on portC then the ph sensor on
portA is it possible for u to provide me the code? but i need to run the motor as following the ph value and stop when the water reach high level.
Re: ph meter using pic 16f877 pls help on coding
ok my reading from my sensor is
2.54V for pH7 water.
so i want the water to maintain at pH7 if lesser or higher i will flush it out using a pump or a dc motor and at the same time i wanna control the water level so it wont over flow when the new...
