Hi hello community!
I'm preparing a design for pH meter.
I've received the samples of LMP91200 pH sensor provided by Ti / National.
We came across a simple question during the reading of the datasheet and application notes.
We are going to use Cortex-M3 LPC1769 as the main processor and we would like to know how the pH measure comes out the sensor.
To clarify that, we need to know how to read the measure value in mv. to be converted in the pH measure at the Cortex processor. Is it enough to connect the Vout PIN to the microprocessor?
Which pH probe do you recommend to use?
Please, if you need any further details on my question, let me know.
This is the most critical part of the design.
Regards,
