Let’s build a simple pH-meter, all we need are Arduino (Uno/Nano/Whatever), PH-4502C and BNC probe. PH Probe Sensor Pinout TO – Temperature output DO – 3.3V pH limit trigger PO – PH analog output Gnd – Gnd for PH probe Gnd – Gnd for board VCC – 5V DC POT 1 – Analog reading offset (Nearest to BNC connector) POT 2 – PH limit setting Calibration This board have the ability to supply a voltage output to the analogue board that will represent a PH value just like any other sensor that will connect to an analog pin.
