High Resolution Pressure Sensor - MS5803-14BA I2C & SPI

Features:

• MS5803-14BA Pressure Sensor Breakout
• High resolution pressure sensor
• Both I2C and SPI interfaces
• MEMS pressure sensor
• Measures the absolute pressure of the fluid around it
• Works for measuring the pressure in air, water, and any other viscous fluids
• Useful for determining altitude, water depth, or any other tasks that require an accurate pressure reading.
• What makes the MS5803-14BA unique is the the gel membrane and antimagnetic stainless steel cap that protects against 30 bar water pressure.
• Resolution range of 1 / 0.6 / 0.4 / 0.3 / 0.2 mbar
• Solder across the two solder points to jump and switch between I2C and SPI interfaces
• Address 0x76 or 0x77 selectable by solder jump for addressing multiple boards at the same time

Specifications:

• Operating Voltage: 1.8V - 3.6V
• Power consumption: 1.4mA
• Communication Protocol: I2C and SPI
• Communication Speed: up to 3.4 MHz via I2C / up to 10 MHz via SPI 3 or 4 wire
• Full calibrated
• Pressure Range: 0hPa to 14000hPa (0 to 14 bar)
• Resolution: 1 / 0.6 / 0.4 / 0.3 / 0.2 mbar
• Gel protected
• With SPI you can connect multiple sensors together without worrying about I2C address collisions
