Classes
- class MeaSpecMS5803
- The Sensor sub-class for the Measurement Specialties MS5803 sensor.
- class MeaSpecMS5803_Temp
- The Variable sub-class used for the temperature output from a Measurement Specialties MS5803 digital pressure sensor.
- class MeaSpecMS5803_Pressure
- The Variable sub-class used for the pressure output from a Measurement Specialties MS5803 digital pressure sensor.
Defines
- #define MS5803_NUM_VARIABLES = 2
- Sensor::
_numReturnedValues; the MS5803 can report 2 values. - #define MS5803_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for a Measurement Specialties MS5803
- #define MS5803_WARM_UP_TIME_MS = 10
- Sensor::
_warmUpTime_ms; the MS5803 warms up in 10ms. - #define MS5803_STABILIZATION_TIME_MS = 0
- Sensor::
_stabilizationTime_ms; the MS5803 is stable as soon as it warms up (0ms stabilization). - #define MS5803_MEASUREMENT_TIME_MS = 10
- Sensor::
_measurementTime_ms; the MS5803 takes 10ms to complete a measurement.
Temperature
The temperature variable from a Measurement Specialties MS5803
- Range is -40°C to +85°C
- Accuracy is ±0.8°C
Construct a new MeaSpecMS5803_
MeaSpecMS5803_Temp(MeaSpecMS5803* parentSense,
const char* uuid = "",
const char* varCode = MS5803_
Parameters
parentSense
The parent MeaSpecMS5803 providing the result values.
uuid
A universally unique identifier (UUID or GUID) for the variable; optional with the default value of an empty string.
varCode
A short code to help identify the variable in files; optional with a default value of "MeaSpecMS5803Temp".
- #define MS5803_TEMP_RESOLUTION = 2
- Decimals places in string representation; temperature should have 2 - resolution is <0.01°C.
- #define MS5803_TEMP_VAR_NUM = 0
- Sensor variable number; temperature is stored in sensorValues[0].
- #define MS5803_TEMP_VAR_NAME = "temperature"
- Variable name in ODM2 controlled vocabulary; "temperature".
- #define MS5803_TEMP_UNIT_NAME = "degreeCelsius"
- Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
- #define MS5803_TEMP_DEFAULT_CODE = "MeaSpecMS5803Temp"
- Default variable short code; "MeaSpecMS5803Temp".
Pressure
The pressure variable from a Measurement Specialties MS5803
- Range is 0 to 14 bar
- Accuracy between 0 and +40°C is:
- 14ba: ±20mbar
- 2ba: ±1.5mbar
- 1ba: ±1.5mbar
- Long term stability is:
- 14ba: -20 mbar/yr
- 2ba: -1 mbar/yr
- Resolution is: (at oversampling ratios: 256 / 512 / 1024 / 2048 / 4096, respectively))
- 14ba: 1 / 0.6 / 0.4 / 0.3 / 0.2 mbar (where 1 mbar = 100 pascals)
- 2ba: 0.13 / 0.084 / 0.054 / 0.036 / 0.024
- 1ba: 0.065 / 0.042 / 0.027 / 0.018 / 0.012
