MS5837-07BA Ultra-small, gel filled dual range pressure sensor, with stainless steel cap

The MS5837-07BA is a high-resolution altimeter sensor from TE
Connectivity with I2C bus interface. The MS5837-07BA26 is the high
endurance pad technology and lid shielded version of this pressure
sensor module.
This sensor is optimized for barometric pressure range but also for water
depth measurement systems with a resolution of 31cm. 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
accurate 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 MS5837-07BA can be interfaced to
virtually any microcontroller. The communication protocol is
straightforward, without the need of programming internal registers in the
device. The gel protection and antimagnetic stainless-steel cap make the
module water resistant. Enhanced construction and design materials
allow for enhanced chemical endurance in applications with harsh liquid
media environments with limited exposure.
Small dimensions of only 3.3 mm x 3.3 mm x 1.7 mm allows integration in
mobile devices. This sensor module generation is based on leading
MEMS technology and latest benefits from TE Connectivity (TE) proven
experience and know-how in high volume manufacturing of altimeter and
high-pressure modules, which has been widely used for over a decade.
