SparkFun Pressure Sensor Breakout

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.
