Kind: Board Level

The MS5840 is an ultra-compact micro altimeter. It is optimized for altimeter and barometric applications. The altitude resolution at sea level is 13 cm of air. The sensor module includes a temperature measurement. The MS5840 can be interfaced to any microcontroller via I2C. The gel protection and antimagnetic stainless steel cap makes this barometric pressure sensor water resistant. 

Small dimensions of only 3.3 mm x 2.2 mm x 1.7 mm allows integration in mobile devices. The MS5840 is an ultra-compact micro altimeter. It is optimized for altimeter and barometric applications. The altitude resolution at sea level is 13 cm of air.
