HI Guys i really am in need of help
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
