+ * 5534 web page</a>
+ * </p>
+ * <blockquote>The MS5534 is a SMD-hybrid device including a
+ * piezoresistive pressure sensor and an ADC-Interface IC.
+ * It provides a 16 Bit data word from a pressure- and
+ * temperature-dependent voltage. Additionally the module
+ * contains 6 readable coefficients for a highly accurate
+ * software calibration of the sensor. MS5534 is a low-power,
+ * low-voltage device with automatic power down (ON/OFF)
+ * switching. A 3-wire interface is used for all communications
+ * with a microcontroller. Sensor packaging options are
+ * plastic or metal cap.
