MXP2300DT1 with Arduino

[anniemm]

Hello,

I am doing a very basic project that integrates the sensor MXP2300DT1 with Arduino Adafruit feather M0 WiFI. On the Arduino IDE, I found only one library named: PRESSUREMPXNXP  which only defines the MPX500 series sensors. My question is:  Do you know if I can use this same library for the MXP2300DT1? Or is it any other library I can use? 

Thanks is advance!

Because of my limited experience with the PRESSUREMPXNXP Arduino library, I suggest you ask your query on the official Arduino support forum.

The MXP2300DT1, on the other hand, is a non-amplified pressure sensor that produces a differential output voltage of only a few millivolts. Combining it with a differential amplifier is the standard method for increasing the single-ended output voltage. MaryKayInTouch

Hello Annie,

I am not very familiar with the PRESSUREMPXNXP Arduino library, I would recommend you to post your question on the Arduino forum.

However, the MXP2300DT1 is a non-amplified pressure sensor with a  differential output voltage in the range of few mV. It usually needs to be coupled with a differential amplifier to achieve a higher single ended output voltage.

Best regards,

Tomas

Thanks for your answer. I figured out the Arduino part. But could you please tell me what would be the output of the sensor in mV for 40Kpa? Is it 3mV?

I already coupled it with an amplifier, but  I am not sure I am getting accurate data.

Do you have a recommendation for the type of amp I should use? 

As of now, I have this one: https://www.amazon.com/gp/product/B07YHYSXR6/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I set it up so 4mV ---> 2V, but when I am testing the sensor I get all sorts of random measurements and I do not have a reference of Kpa to compare.
