Readings fluctuate and always show the same several counts

Other Hardware Sensors

I have a MS4525DO sensor and want tot run it for airspeed.
I have write the code below and try to make it work
The data responds to the wind I blow into it. However, the result for digital counts and airspeed always show the same several counts when I vary the windspeed
and also the readings are fluctuate

Can someone help?

datasheet

//#include <WireMW.h>
#include <Wire.h>   //I2C library 0x28H 

#define TRUE 1
#define FALSE 0


void setup()
{
  Serial.begin(9600);
  Wire.begin();
  delay(100);
  Serial.println ("Digital Count \t Pressure \t Wind Speed");
}

void loop() {
   byte Address, Press_H, Press_L;
   Address = 0x28; //ms4525do type I interface address
   int DC;
   double PR,V;
   
  Wire.beginTransmission(Address);
  Wire.endTransmission();
  
  Wire.requestFrom(Address,2);
  Press_H = Wire.read();
  Press_L = Wire.read();
  DC =  ( ( (Press_H << 8) + Press_L ) & 0x3FFF); //In 14bit binary-coded the real value must be computed
  PR = ((DC-0.1*16383)*2/(0.8*16383)-0.992599035);
  V = sqrt(abs(PR*2*6894.757/1.225));

   
   
   Serial.print (DC);
   Serial.print ("\t");
   Serial.print (PR);
   Serial.print ("\t");
   Serial.println (V);
    delay(1000);

}

I'm sure the output shown in the picture is not from above sketch. Please post the correct code!

How did you get to these formulas?

  PR = ((DC-0.1*16383)*2/(0.8*16383)-0.992599035);
  V = sqrt(abs(PR*2*6894.757/1.225));

Which exact type of that sensor do you have?

Why don't you print the status bits (bit 14 and 15 of the I2C read)?

Indeed, screen output and sketch don't match up.

Also please copy/paste your screen output and post it between code tags, just like you post your code. Much more readable than a photo of a screen.
