MIKROE 3195 Analogue output issue

[Abhishek_Gaikar]

I am currently working with MIKROE 3195 board consisting of MPVX6115 sensor from NXP for pressure measurement. The board's analog output isn't showing much fluctuations even after a large change in the pressure applied in my system. The system jumpers are at factory position VOUT jumper = 1v8 position I/O select = 3v3 position I'm using the Raspberry Pi Pico's ADC in order to read the analog output.

The formula I've used for conversion is P = [(VOUT / VS) - 0.92] / 0.007652 +- 1.725 kPa.

Could you please help me with this

Hello,

Please find the transfer function in the datasheet page 6.

VOUT = VS x (0.007652 x P + 0.92) ± (Pressure Error x Temp. Factor x 0.007652 x VS)

Hope this helps.
