MS5837-30BA
Overview
The MS5837-30BA is a high-resolution absolute pressure sensor from TE Connectivity designed for deep-water and high-pressure environments. It provides 24-bit digital pressure and temperature data via an I2C interface, featuring a gel-filled cavity and anti-magnetic stainless steel cap to ensure reliability in harsh underwater conditions. This sensor is optimized for water depth measurements with a maximum operating pressure of 30 bar.
Why Choose This Part
The sensor offers a wide 30 bar pressure range while maintaining a high 24-bit resolution, allowing for precise measurements even at significant depths. Its ultra-low power consumption and wide supply voltage range (1.5V to 3.6V) make it ideal for battery-powered mobile applications. The shielded, gel-protected design provides high endurance against environmental contaminants.
Applications
Key Specifications
Getting Started
Interface the sensor with a microcontroller using the I2C bus (address 0x76) and ensure the supply voltage does not exceed 3.6V. Since this is an un-ported surface mount module, mechanical integration requires careful consideration of O-ring sealing to protect the host PCB from liquid ingress. Manufacturers typically provide C libraries for reading the factory-stored calibration constants and performing the necessary pressure/temperature compensation calculations.
