Product Details

This is the MS5803-14BA Pressure Sensor Breakout, a high resolution pressure sensor with both an I2C and SPI interface.
This Pressure Sensor Features: Operating Voltage - 1.8 to 3.6V. Peak Supply Current - 1.4 mA. Operating Range - 0 to 14 bar. Resolution - 1 / 0.6 / 0.4 / 0.3 / 0.2 mbar. I2C and SPI Interface. Gel Protected.
We have broken out all the pins you need including GND and 3.3V for power, SDA/SDI and SCL/SCLK for an I2C interface and SD0, AD/CS, and PS for a SPI interface. The MS5803-14BA Breakout offers a resolution range of 1 / 0.6 / 0.4 / 0.3 / 0.2 mbar.
You'll need to modify the jumpers on the board for SPI mode by removing solder from the pull-up resistors jumper pads and close the other two jumpers. Additionally, you will need to write a library to communicate with the MS5803 in SPI mode if you plan on using this compatible with Arduino.
This MEMS pressure sensor measures the absolute pressure of the fluid around it which includes air, water, and anything else that acts like a viscous fluid. Depending on how you interpret the data, you can determine altitude, water depth, or any other tasks that require an accurate pressure reading.
