The MS5837 is a new generation of high resolution pressure sensors with an I2C bus interface with a water depth resolution of 2 mm for depth measurement systems.
Overpressure 50 bar
Sensor Type Digital Pressure and Height Sensor Module
Type absolute pressure
Output / Span 24-bit ADC
The sensor module includes a high linear pressure sensor and an ultra low power 24-bit ΔΣ ADC with internal factory calibration coefficients. Provides accurate 24-bit digital pressure and temperature values and different operating modes, allowing users to configure conversion speed and current consumption as needed. The high resolution temperature output allows you to implement deep measurement systems and thermometers without the need for additional sensors.
The MS5837 can be connected to almost any microcontroller. The communication protocol is simple and there is no need to program the internal registers in the device. The gel protection and anti-magnetic stainless steel caps ensure that the sensor module is water resistant. This new sensor module is based on advanced MEMS technology and benefits from MEAS Switzerland's proven experience and expertise in high volume manufacturing over the past decade

Most customers of this product are sounding:
02 represents the measuring range, which is 2 kg, corresponds to a water depth of 20 meters, and can measure up to 100 meters.
30 represents the measuring range, which is 30 kilograms, corresponding to a water depth of 300 meters, and the maximum measurement is 500 meters
Many customers only measure tens of meters, but he chose 30BA, which is 300 meters. Use a 300-meter sensor to monitor a depth of tens of meters, which will sacrifice resolution and accuracy, and will not be accurate. Need to choose 02BA, choose according to requirements
If you choose to test the air pressure, then 02BA and 30BA can be
