MS5837 digital absolute pressure sensor by AMSYS

MS5839 digital absolute pressure sensor

The MS5839 is a digital OEM sensor* that measures the absolute pressure* with high resolution. It is compensated and outputs the measured values as digital output signals via an I²C interface.

The reflowable sensors are designed for the pressure range of 300 – 1200 mbar (MS5839-02BA36) and are media-protected with a chlorine resistant gel coating. They are also shielded. In addition to the pressure, they measure the temperature from -40 to 85 ° C.

The MS5839 pressure sensors consist of a piezoresistive pressure cell and an amplifier A/D-interface-IC, housed in a QFN package (3.3 x 3.3 x 2.75 mm³). The metal top protects the electronic components and facilitates O-ring mounting. The sensor converts the measured pressure- and temperature-dependent signal of the measuring cell into a 24-bit data word. 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.

Accessory for the MS5839

Also available is the grove board, which can be used to quickly evaluate the sensors and build prototypes.
