The MS5637 is an ultra-compact micro altimeter. 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 ÎΣ 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 I2C-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.
The sensing principle employed leads to very low hysteresis and
high stability of both pressure and temperature signal.
