1Set Liquid PH 0-14 Value Detection Regulator Sensor Module Control Meter TestV2 (1) First connect the PH electrode through the BNC connector, and then connect the PH sensor module to the power supply according to the introduction diagram. The output terminal of the PH sensor is analog output. Connect to the ADC conversion device, such as the ARUDUINO analog input port. After the connection is made, after powe the for Arduino main controller, you can see the pH meter r r r The red indicator light of the circuit board turns on. (2) Write sample code to for Arduino main controller. (3) Insert the pH electrode into the standard solution with a pH value of 7.00, or directly short-circuit the two inputs of the BNC interface, and open the serial port of o for Arduino IDE, On the monitor, you can see the pH value currently printed, and the error will exceed 0.3. Record the value printed at this time, and then compare with 7.00, modify the difference to At t Offset in the program. For example, if the printed pH value is 6.88, the difference is 0.12, then in the sample program, change e #define t Offset 0.00 to e #define t Offset 0.12. (4) Insert the pH electrode into the calibration solution with a pH value of 4.00, wait for one minute, then adjust the gain potentiometer to make the printed pH value as stable as 4.00 Around. At this point, the acid section calibration has been completed, and you can test the pH value of the acid solution. e: When measu other solutions, the electrode must be cleaned. (5) Relying on the linear characteristics of the pH electrode itself, after the above calibration, the pH value of the alkaline solution can be directly measured, but if you want to obtain better accuracy, It is recommended to recalibrate. The alkaline section calibration uses a standard solution with a pH of 9.18, and also adjusts the gain potentiometer to stabilize it at about 9.18. After calibration, At this poi
