Overview

It is optimized for altimeter and barometer applications in Smart-phones and Tablet PCs. The altitude resolution at sea level is 13 cm of air. 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 MS5637 can be interfaced to any microcontroller with I 2 C-bus interface. The communication protocol is simple, without the need of programming internal registers in the device. Small dimensions of 3 x 3 x 0.9 mm3  allow the integration in mobile devices. This new sensor module generation  is  based on leading MEMS technology and latest benefits from MEAS Switzerland proven experience and  know-how in high volume manufacturing of altimeter modules, which has been widely used for over a decade.
