  Demo Program for MS5803 pressure sensors.

  https://github.com/sparkfun/MS5803-14BA_Breakout/

  The MS58XX MS57XX and MS56XX by Measurement Specialties is a low cost I2C pressure

  sensor.  This sensor can be used in weather stations and for altitude

  estimations. It can also be used underwater for water depth measurements.

  Resources:

  This library uses the Arduino Wire.h to complete I2C transactions.

  Development environment specifics:

IDE: Arduino 1.0.5

Hardware Platform: Arduino Pro 3.3V/8MHz

T5403 Breakout Version: 1.0

**Updated for Arduino 1.8.8 5/2019**

  This code is beerware. If you see me (or any other SparkFun employee) at the

  local pub, and you've found our code helpful, please buy us a round!

  Distributed as-is; no warranty is given.
