I have a MPX5700GP pressure sensor, it has a 0- 700kPa gauge pressure range and a 0-5V output voltage.
The sensitivity is 6.4mV/kPa. its my design project for college.
My problem is I dont know how to take the volages and compensate the values accordingly, the output voltage on the sensor compared to the values displayed serially are not the same.
if my sensor is reading no pressure. the voltage output is 0.20V but if i display the analog value it shows 40.
im really lost. could somebody help me. i have recorded a range of values with pressure accordingly. if any data is needed. i will send. please help
16 is because that is a number that balances the extra time and the result quite well for most sensors I have used. The averaging is not strictly needed as you can handle noise also otherwise e.g. by a low pass filter.
okay thanks guys, but im still not getting the pressure values on the serial monitor. im getting so stressed out here. please any advice. am i making a mistake or is there a problem with my arduino?

Can you be a little more specific of what exactly is stressing you out? What is your expectations Vs what you are getting? And of course your code will be to be seen to offer any corrections if indeed there are correction needed.
Hello folks,
I am using G1/4 Pressure Transmitter Sensor 0-1.2 MPa sensor can you guide for programming part.The conversion of bar to pascal or bar to Mpa or pascal to psi.Though I am new to it.Plz guide me .
