TE Connectivity / Measurement Specialties MS5837-02BA Gel-Filled Pressure Sensor Modules

TE Connectivity's Measurement Specialties MS5837-02BA Pressure Sensor Modules are ultra-small gel-filled pressure sensors optimized for altimeter and barometer applications. These pressure sensor modules feature a robust package, enabling them to withstand harsh environments. TE's MS5837-02BA MEMS-based sensor includes a high-linearity pressure sensor with an ultra-low-power 24-bit digital output (I2C) and an altitude resolution at sea level of 13cm. This TE series enables high-resolution measurements such as counting flights of stairs.

These ultra-compact micro altimeter series allows for design flexibility and is a compact gel-filled watertight sensor. The robust sensor package consists of ceramic and metal materials. A high-resolution temperature output allows the implementation of a thermometer ion without any additional sensor.
