Arduino library for the MS5837 pressure sensor. The MS5837 is a tiny SMT pressures sensor from Measurement Specialties that can measure pressure of up to 30 Bar (300m depth) with resolution of 0.2 mbar.
This library also supports the MS5837-02BA which has a much smaller measurement range and is better suited for altitude measurement in air.
Please see the examples for normal operation. Below are the available functions used in the library.
MS5837();
/** Must be called before attempting to operate the sensor. * Returns true if the sensor was initialized successfully.*/boolinit();
/** Set model of MS5837 sensor. Valid options are MS5837::MS5837_30BA (default) * and MS5837::MS5837_02BA.*/voidsetModel(uint8_t model);
/** Provide the density of the working fluid in kg/m^3. Default is for * seawater. Should be 997 for freshwater.*/voidsetFluidDensity(float density);
/** The read from I2C takes up for 40 ms, so use sparingly is possible.*/voidread();
/** Pressure returned in mbar or mbar*conversion rate.*/floatpressure(float conversion = 1.0f);
/** Temperature returned in deg C.*/floattemperature();
/** Depth returned in meters (valid for operation in incompressible * liquids only. Uses density that is set for fresh or seawater.*/floatdepth();
/** Altitude returned in meters (valid for operation in air only).*/floataltitude();
