Description:

Analogue pH sensor, specially designed for Arduino controllers is easy to use and can be used as a plug-and-play solution to measure the pH value of a solution without any additional circuit required. Instant connection to your probe your Arduino to get pH measurements at ± 0.01pH. For most hobbyists, this great accuracy range and its low cost make this a great tool for bio-robotics and other projects! It has an LED which works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface. To use it, just connect the pH sensor with the BND connector, and plug the PH2.0 interface into the analogue input port of an Arduino controller. With a simple program to the ready analogue voltage, you will get the pH value easily. Comes in a compact plastic box with foams for better mobile storage.

Step to use the pH Meter:

Cautions:

  • Please use an external switching power supply, and the voltage as close as possible to the +5.00V. More accurate the voltage, the higher the accuracy!
  • Before the electrode is in continuous use every time, you need to calibrate it by the standard solution, in order to obtain more accurate results. The best environment temperature is about 25, and the pH value is known and reliable, close to the measured value. If you measure the acidic sample, the pH value of the standard solution should be 4.00. If you measure the alkaline sample, the pH value of the standard solution should be 9.18.Subsection calibration, just in order to get better accuracy.
  • Before the pH electrode measured different solutions, we need to use water to wash it. We recommend using deionized water.
  1. Connect equipment according to the graphic, that is, the pH electrode is connected to the BNC connector on the pH meter board and then uses the connection lines, the pH meter board 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.
  2. Upload the sample code to the Arduino controller.
  3. Put the pH electrode into the standard solution whose pH value is 7.00or directly shorted the input of the BNC connector. Open the serial monitor of the Arduino IDE, and you can see the pH value printed on it, and the error does not exceed 0.3. Record the pH value printed, then compared with 7.00, and the difference should be changed into the Offset in the sample code. For example, the pH value printed is 6.88, so the difference is 0.12. You should change the # define Offset 0.00 into # define Offset 0.12 in your program.
  4. Put the pH electrode into the pH standard solution whose value is 4.00. Then wait about one minute, adjust the gain potential device, and let the value stabilize at around 4.00. At this time, the acidic calibration has been completed and you can measure the pH value of an acidic solution.

Note: If you want to measure the pH value of other solutions, you must wash the pH electrode first!

  • According to the linear characteristics of the pH electrode itself, after the above calibration, you can directly measure the pH value of the alkaline solution, but if you want to get better accuracy, you can recalibrate it. The alkaline calibration uses the standard solution whose pH value is 9.18. Also, adjust the gain potential device, and let the value stabilize at around 9.18. After this calibration, you can measure the pH value of the alkaline solution.
