public Walrus()

Instantiate Walrus object.

public uint8_t begin(uint8_t Address_)

Begin communications with the Walrus using a prescribed address.

Parameters

• Address_ I2C address of Walrus DOES NOT YET USE A VARIABLE ADDRESS! THIS DEFAULT ADDRESS CURRENTLY CLASHES WITH HAAR'S DEFAULT!

public float getTemperature(uint8_t Location)

Return calculated temperature from Walrus.

This calculated temperature can be from either the MS5803 sensor, which primarily measures pressure, or from the

Parameters

• Location TEMP_REG_0: Read dedicated temperature sensor. TEMP_REG_1: Read temperature sensor withn the MS5803. APPEARS TO JUST WORK WIHT TEMP_REG_0 FOR NOW

public float getTemperature()

Return calculated temperature from sensor, using a predefined offset. WHAT DOES THIS OFFSET DO?

public float getPressure()

Return calculated pressure from sensor.

This is the MS5803 sensor, which can come in a variety of different pressure ranges and sensitivities.

public String getHeader()

Return header.

"Pressure [mBar],Temp DH [C],Temp DHt [C],"

public String getString()

Return measurement data as a string.

String(getPressure()) + "," + String(getTemperature(0))

• "," + String(getTemperature(1)) + ",";
