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. */ bool init(); /** Set model of MS5837 sensor. Valid options are MS5837::MS5837_30BA (default) * and MS5837::MS5837_02BA. */ void setModel(uint8_t model); /** Provide the density of the working fluid in kg/m^3. Default is for * seawater. Should be 997 for freshwater. */ void setFluidDensity(float density); /** The read from I2C takes up for 40 ms, so use sparingly is possible. */ void read(); /** Pressure returned in mbar or mbar*conversion rate. */ float pressure(float conversion = 1.0f); /** Temperature returned in deg C. */ float temperature(); /** Depth returned in meters (valid for operation in incompressible * liquids only. Uses density that is set for fresh or seawater. */ float depth(); /** Altitude returned in meters (valid for operation in air only). */ float altitude();
