Arduino Ph Sensor Kullanımı. Ph sensor for arduino. The ph sensor interface circuit is also provided with 6 male headers which are clearly labeled as v this is where we connect the 33v or 5v from the arduino in my case i will connect 5 volts but if you are planning to use this ph sensor kit with esp8266 or esp32 then you will need to connect this pin with 33volts.
We have to change negative potential to positive potential. As explained in my previous tutorial which is. Neutral ph7 set to 0v this means that the voltage will go into the minuses when reading acidic ph values and obviously cannot be read by the analog arduino port.
E compile and upload the code to the arduino.
As arduino cannot read negative potential directly so we need proper calibration. Kabel ke mikrokontroler example. Free delivery available view our range and shop now online. In other words ph is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative ph value.
