The MS5637 is a digital OEM sensor that measures absolute pressure and ambient temperature with high resolution. The sensor is compensated and outputs the measured values as digital output signals via an I²C interface.
The reflowable sensor MS5637-02BA03 is designed for the pressure range of 10 – 2000 mbar, but optimized for the pressure range 300 – 1200 mbar. The newer version of the MS5637-30BA is designed for the range 0-30 bar and optimized for the range 0.3 – 14 bar. In addition to the pressure, the sensors measure the temperature from -40 to 85 ° C.
The MS5637 pressure sensors consist of a piezoresistive pressure cell and an amplifier A/D-interface-IC, housed in a QFN package (3.0 x 3.0 x 0.9 mm³). The sensor converts the measured pressure- and temperature-dependent signal of the measuring cell into a 16-bit data word. In addition, 6 individual coefficients are stored in the sensor, which allow the highly accurate software correction for the pressure and temperature measurement by an external microprocessor. The I²C interface is used for serial communication with the microprocessor.
The sensors are intended for applications with a digital system environment. Since there is already a processor at system level, this can be used to easily calculate the current pressure and temperature values.
