MS5611
Arduino library for MS5611 temperature and pressure sensor
Description
The MS5611 is a high resolution temperature and pressure sensor. The high resolution is made possible by oversampling (many times).
0.3.0 breaking changes
- fixed math error so previous versions are obsolete
- temperature is a float expressed in degrees Celsius.
- pressure is a float expressed in mBar.
Interface
- MS5611(uint8_t deviceAddress) constructor
- bool begin(uint8_t sda, uint8_t scl, TwoWire *wire = &Wire) for ESP and alike, optionally set Wire interface. initializes internals,
- bool begin(TwoWire *wire = &Wire) for UNO and alike, optionally set Wire interface. Initializes internals
- bool isConnected() checks availability of deviceaddress on the I2C bus.
- reset() resets the chip and loads constants from it.
- int read(uint8_t bits = 8) the actual reading of the sensor. Returns MS5611_READ_OK upon success
- float getTemperature() returns temperature in °C. Subsequent calls will return same value until a new read() is called.
- float getPressure() pressure is in mBar. Subsequent calls will return same value until a new read() is called.
- int getLastResult() checks last I2C communication (replace with more informative error handling?)
- uint32_t lastRead() last time in millis() when read() was called.
Disclaimer
The library is experimental. As I have no such sensor the quality is hard to test. So if you happen to have such a sensor, please give it a try and let me know.
TODO
- proper error handling
- redo lower level functions?
- SPI version?
