Classes

class BoschBMP3xx

The Sensor sub-class for the Bosch BMP3xx.

class BoschBMP3xx_Temp

The Variable sub-class used for the temperature output from a Bosch BMP3xx.

class BoschBMP3xx_Pressure

The Variable sub-class used for the atmospheric pressure output from a Bosch BMP3xx.

class BoschBMP3xx_Altitude

The Variable sub-class used for the altitude calculated from the measurements made by a Bosch BMP3xx.

Defines

#define BMP3XX_NUM_VARIABLES = 3

Sensor::_numReturnedValues; the BMP3xx can report 3 values.

#define BMP3XX_INC_CALC_VARIABLES = 1

Sensor::_incCalcValues; altitude is calculted within the Adafruit library.

#define SEALEVELPRESSURE_HPA = (1013.25)

The atmospheric pressure at sea level.

Sensor Timing

The sensor timing for a Bosch BMP3xx

#define BMP3XX_WARM_UP_TIME_MS = 3

Sensor::_warmUpTime_ms; BMP3xx should be ready to communicate within 3ms.

#define BMP3XX_STABILIZATION_TIME_MS = 4000

Sensor::_stabilizationTime_ms; BMP3xx is stable after 4000ms.

#define BMP3XX_MEASUREMENT_TIME_MS = 80

Sensor::_measurementTime_ms; The number given in this define will be recalculated and over-written in the set-up.

Temperature

The temperature variable from a Bosch BMP388 or BMP390

• Range is -40°C to +85°C
  • Full accuracy between 0°C and +65°C
• Absolute accuracy is typ. ± 0.5°C at 25°C
  • ± 1.5°C over 0°C to +65°C range

#define BMP3XX_TEMP_RESOLUTION = 2

Decimals places in string representation; temperature should have 5 - resolution is 0.0.00015°C at the hightest oversampling. See table 7 in the sensor datasheet for resolution at all bandwidths.

#define BMP3XX_TEMP_VAR_NUM = 0

Sensor variable number; temperature is stored in sensorValues[0].

#define BMP3XX_TEMP_VAR_NAME = "temperature"

Variable name in ODM2 controlled vocabulary; "temperature".

#define BMP3XX_TEMP_UNIT_NAME = "degreeCelsius"

Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)

#define BMP3XX_TEMP_DEFAULT_CODE = "BoschBMP3xxTemp"
