This combo is specially designed for Arduino controllers. It has an LED which works as the Power Indicator, a BNC connector and PH sensor interface. It is very easy to use. The electrode is made of a pH glass electrode and a reference electrode combined composite electrode, which is pH meter measuring sensor for measuring the concentration of an aqueous solution of H (pH value), it is widely used in various fields to be detected in the pH. The PH electrode has a single cylinder that allows direct connection to the input terminal of a PH meter, controller, or any PH device which has a BNC input terminal. The PH electrode probe is accurate and reliable that can give almost instantaneous readings.
Operating Voltage is 5V DC.
The best environment temperature is about 25 degree.
The pH Probe is connected to the BNC connector on the pH Sensor Module，and then use the connection lines,PH Sensor Module is connected to the analogue port 0 of the Arduino controller.
When the Arduino controller gets power, you will see the blue LED on board is on.
Upload the sample code to the Arduino controller.
Put the PH Probe into the standard solution. Open the serial monitor of the Arduino IDE, you can see the pH value printed on it
If you want to measure the pH value of other solution, you must wash the pH electrode first.
1 x PH Electrode Probe
1 x PH Value And Temperature Detection Sensor Module
