Product Descriptions

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. Thesensor 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 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.
