The MS5803-01BA is a new generation of high resolution
altimeter sensors from Measurement Specialties with SPI and I²C
bus interface. The MS5803-01BA HE is the high endurance pad
technology version of the MS5803-01BA pressure sensor module.
It is optimized for altimeters and variometers with an altitude
resolution of 10 cm. The sensor module includes a high linearity
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 an altimeter/thermometer function without
any additional sensor. The MS5803-01BA can be interfaced to
virtually any microcontroller. The communication protocol is
simple, without the need of programming internal registers in the
device. The gel protection and antimagnetic stainless steel cap
allows the use in 100m water resistant altimeter/compass
watches. This new sensor module generation is based on leading
MEMS technology and latest benefits from MEAS proven
experience and know-how in high volume manufacturing of
altimeter modules, which have been widely used for over a
decade. The sensing principle employed leads to very low
hysteresis and high stability of both pressure and temperature
