+  * </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.
