MS5637-30BA Digital Pressure & Altimeter Sensor

Brand: American Sensor Technologies Inc
Request Information Favorite
The MS5637-30BA is a new generation of high resolution miniature industrial pressure sensors from MEAS Switzerland with I²C bus interface. 

It is optimized for air pressure measurement systems with a resolution of 0.5 mbar. The sensor module includes a highly linear 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 a pressure measurement systems and thermometer function without any additional sensor. The MS5637-30BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need to programming internal registers in the device. The antimagnetic stainless steel cap protects the pressure die. 

This new sensor module generation is based on leading MEMS technology and latest benefits from the MEAS Switzerland proven experience and know-how in high volume manufacturing of pressure modules have been widely used for over a decade.
