MPX5999D

General description

The MPX5999D piezoresistive transducer is a state-of-the-art pressure sensor designed for a wide range of applications, but particularly for those employing a microcontroller or microprocessor with A/D inputs. This patented, single element transducer combines advanced micromachining techniques, thin-film metallization and bipolar semiconductor processing to provide an accurate, high level analog output signal that is proportional to applied pressure.

Feature

Temperature Compensated Over 0 to 85 °C
Ideally Suited for Microprocessor or Microcontroller-Based Systems
Patented Silicon Shear Stress Strain Gauge
Durable Epoxy Unibody Element

Application

OSS-ECAL specification

Pressure 0 to 1000 [kPa]

etCMD
eCMD_START

Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oMPX5999D_START( void )

Return value :
eSTS_FIN
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT

NOTE :
Arduino, Mbeb, ModusToolbox not supported.

eCMD_READ

Feature :
Command that reads the AD conversion value, converts the AD conversion value to a characteristic Pressure, and stores the Pressure in rlt.

Process :
1. Read AD conversion value.
2. Convert AD conversion value to Pressure.
Voltage value = (AD conversion value × VDD) / (2^{AD bit} )
Pressure = ((voltage value – voltage offset value) / gain) + Pressure offset value (Min, Max Limit)
3. Store Pressure to rlt.

Command API function :
etSTS oMPX5999D_READ( float32* rlt )

Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT

NOTE :
Please execute this API function after starting AD conversion.
Arduino, Mbeb, ModusToolbox not supported.

eCMD_START_READ

Feature :
Command that starts AD conversion, waits for AD conversion to finish, reads out the AD conversion value, converts the AD conversion value to a characteristic Pressure, and stores the Pressure in rlt.

Process :
1. Read AD conversion value.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Pressure.
Voltage value = (AD conversion value × VDD) / (2^{AD bit} )
Pressure = ((voltage value – voltage offset value) / gain) + Pressure offset value (Min, Max Limit)
5. Store Pressure to rlt.

Command API function :
etSTS oMPX5999D_START_READ( float32* rlt )

Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT
