Open Source PH Meter: An analog PH meter specially designed for Arduino controller, with simple connection and program control, which is very convenient to measure the PH value of the solution.
PH Composite Electrode: a plastic non-fillable composite electrode that uses a combination of a glass electrode and a reference electrode. It is a measuring element for a PH meter and is used to measure the hydrogen ion activity (PH) in an aqueous solution. The figure is a manual for convenient secondary development.
Interface Wiring: BNC/XH2.54 interface; with onboard power indicator. The pH sensor is connected to the onboard BNC interface, and the onboard XH2.54 interface is connected to the analog port of the controller.
Note: It is the most accurate under the condition of 25℃/5V (the closer to this condition, the more accurate); the practical electrode needs to be checked (when measuring acidic/alkaline solutions, use PH-4/PH-9.18 buffer solution for calibration)
