The MS5803- 30A HE is the high endurance pad technology version of the MS5803-30BA pressure sensor module. It is optimized for depth measurement systems with a water depth resolution of 2.5cm and below. The sensor module includes a high linear pressure sensor and  an  ultra  low  power  24  bit  ΔΣ  ADC  with  internal  factory calibrated coefficients. It provides a precise digital 24 Bit pressure and temperature value and different operation modes that allow the   user   to   optimize   for   conversion   speed   and   current consumption.  A  high  resolution  temperature  output  allows  the implementation    of    a    depth    measurement  systems    and thermometer function without any additional sensor. The MS5803-30BA    can    be    interfaced    to    any    microcontroller. The communication   protocol   is   simple,   without   the   need   to programming internal registers in the device. The gel protection and  antimagnetic  stainless  steel  cap  make  the  module  water resistant. This new sensor module generation is based on leading MEMS technology  and latest benefits from MEAS  Switzerland's proven experience and know-how in high volume manufacturing of pressure modules have been widely used for over  a decade. This sensing principle employed leads to very low hysteresis and high stability of both pressure and temperature signal.
