PMS5637
DESCRIPTION

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 16 cm of air. The sensor module includes a high-linearity pressure sensor and an ultra low power 24 bit ΣΔ- A/D 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 für 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 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.

The MS5637 is also offered by AMSYS mounted on a PCB called PMS5637 facilitating the testing and the setup of prototypes.

*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
