I tried to interface the unit with a processor and could not complete the connection as there was no output signal measured. I was able to download the schematic and out that the identification marks on the IC had been erased. The type of the chip was not readable. On the basis of the schematic, I bought the specified IC and replaced it after some arduous work for my 80 year old hands. The specified replacement works. As I have had extensive dealings with Banggood over the past few years in which when delivered the goods were of quality and functioned well, I find that the supplier cheated you and me,, and I do expect some form of corrective action from Banggood for this imposition.

Please forward to mgranot@hotmail.com the instruction manual and directions for calibrating the probe for a standard buffer solution. What is the correlation between the pH of the solution and the voltage output - is it linear? The probe and circuitry are what I need - but I lack the requested data to integrate the probe into the system. Your expeditious response would be most appreciated.

Received the piece of electronics. The sensor itself was missing from the delivery. So it's not gonna do me any good. I made a call to an employee in California who couldn't be heard. Very flawed English.

Het stukje elektronica ontvangen. De sensor zelf ontbrak bij de levering. Dus ik heb er zo nog niets aan. Ik heb gebeld met een medewerker in California die niet was te verstaan. Zeer gebrekkig Engels.

The sensor is working, I calibrated on 6 points, it is also accurate enough. Good product.

works as expected, reasonably accurate, is prone to interference, for example from an EC sensor or other electrical equipment.

Everthing is working fine. Instructions in the box are in Chinese. But they provided voltage and resistance tables, which can be read easily.

Everything is good but there is no description. Neither on the pins, power supply connection method
