MS5637-02BA03

Low Voltage Barometric Pressure Sensor

TE Connectivity Measurement Specialties

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 13cm 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.

Product Description

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 3mm x 3mm x 0.9mm³ 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 knowledge 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 pressure and temperature signal.
