This PH Sensor Module + PH Probe is specially designed for Arduino based controllers. It has an LED which works as the Power Indicator, a BNC connector and PH sensor interface. It is very easy to use.
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 analog port of the controller.
When the controller gets power, you will see the blue LED on board is on.
Upload code to the 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.
