For consumer goods such as mobile water depth measurement systems, diving computers, adventure or multi-mode watches and dataloggers, the MS5837-30BA is a high-resolution pressure sensor with I²C bus interface for depth measurement systems with a water depth resolution of 2 mm.
Made by Measurement Specialties, the sensor module includes a high-linearity pressure sensor and an ultra-low-power, 24-bit delta-sigma analog to digital converter with internal, factory calibrated coefficients. It provides a precise digital 24-bit pressure and temperature value and different operating modes that allow the user to optimise for conversion speed and current consumption. A high-resolution temperature output allows integration of thermometer functionality without an additional sensor.
The device can interface to virtually any microcontroller over a simple communication protocol, without the need to program internal registers in the sensor. It is water resistant thanks to gel protection and an antimagnetic stainless steel cap.
