MS5801-01BA Altimeter Module

DESCRIPTION

The MS5801-01B is a new generation of high resolution altimeter sensors with SPI & I2C interface. It is optimized for depth meters and altimeters with an altitude resolution of 10 cm. The sensor module includes a high linearity pressure sensor and an ultra low power 24 bit ADC with internal factory calibration coefficients. It provides a precise digital 24 bit pressure and temperature value and different operation modes that allow the user to optimize for conversion spped and current consumption. A high resolution temperture output allows the implementation of a thermometer function with no additional sensor. Gel protection and an antimagnetic stainless steel cap allows the use in 100m waterproof altimeter/compass watches.
