MS5837-30BA Digital Pressure & Altimeter Sensor

Brand: American Sensor Technologies Inc
The MS5837-30BA is a new generation of high resolution pressure sensors with I²C bus interface for depth measurement systems with a water depth resolution of 2 mm.

The sensor module includes a high linearity 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 in depth measurement systems and thermometer function without any additional sensor. The MS5837-30BA can be interfaced to virtually any microcontroller.

The communication protocol is simple, without the need of programming internal registers in the device. The gel protection and antimagnetic stainless steel cap make the module water resistant.

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, which has been widely used for over a decade.
