Function Documentation

int16_t mpxx6115a_press ( adcread_t  vout,
adcread_t  vref 
) [inline]

Convert read voltage from MPXX6115A Pressure Sensor in hPascal value.

The conversion formula may be consulted on constructor datasheet (see Freescale Semiconductor MP3H6115A, MPXAZ6115A).

Parameters:
voutoutput voltage read from pin sensor.
vrefreference voltage that supplies the MPXX6115A sensor.
Returns:
integer value that represent measured pressure in hPascal.
Note:
: To compute the pressure we use the Vout/Vref ratio, so these two values can be expressed in any unit, even ADC levels.
