Overview

The MS5540C is a miniature version of the MS5534C barometer/altimeter module and provides a 16-Bit data word from a pressure and temperature dependent voltage.  Compared to MS5534A, the pressure range (measurement down to 10 mbar) has been improved. The MS5540C is fully software compatible to the MS5534C and previous versions of MS5540. In addition, the MS5540C is compatible to the MS54XX series of pressure sensors. The gel protection of the sensor provides a water protection sufficient for 100 m waterproof watches without any additional protection.
