• Easy to use: Communicates via a standard I2C interface.

The MS5837-02BA06 integrates a pressure sensor and a signal conditioning IC in a small package. The sensor converts pressure to an analog voltage, which is digitized by a 24-bit delta-sigma ADC. The digitized values are then available through the I2C interface. The gel filling protects the sensor from water damage and corrosion, making it reliable for long-term underwater use. The sensor also incorporates temperature compensation for accurate measurements across a range of temperatures.

Its resilience and accurate performance make the MS5837-02BA06 an ideal choice for applications requiring precise depth sensing in challenging underwater conditions.
