Overview

The MS5837-02BA is a compact, high-resolution digital pressure sensor optimized for underwater applications requiring precise depth measurement at shallow depths. It provides 24-bit pressure and temperature data via an I2C interface, featuring integrated temperature compensation to ensure accuracy across its operating range. This surface-mountable module is ideal for applications where space is critical.

Why Choose This Part

This sensor offers excellent accuracy of +/-0.05kPa and 24-bit resolution, ensuring precise measurements. Its temperature compensation minimizes drift across an operating temperature range of -20C to 85C. The small 3.3mm x 3.3mm surface mount package makes it suitable for integration into space-constrained designs, and the I2C interface simplifies digital integration.

Applications

Diving Computers and Equipment
Provides accurate depth readings in diving computers and other underwater instrumentation, leveraging its high resolution at shallow depths.
Underwater Drones and ROVs
Enables precise depth control and navigation for autonomous and remotely operated underwater vehicles due to its compact size and digital output.
Weather Stations and Environmental Monitoring
Suitable for measuring atmospheric or contained gas pressure in environmental monitoring systems where a 2 bar range is sufficient and high accuracy is needed.
