v0.2.4

This release adds support for reading the BME680's gas resistance sensor. In the
future, this will be converted to an indoor air quality measurement.

• API changes

  • Sensor measurements are now obtained by calling BMP280.measure/1 for
    consistency with other Elixir sensor libraries. BMP280.read/1 is
    deprecated.

• Improvements

  • The library now polls the sensor once a second. Calls to BMP280.measure/1
    return the latest reading rather than making an I2C transaction.
  • Measurements now include a timestamp (System.monotonic_time(:millisecond))
  • Various internal code improvements to make it easier to support many Bosch
    sensors
