Frequently Asked Questions

What is the operating voltage range for the MS5803-01BA01 sensor?

The MS5803-01BA01 operates from a supply voltage of 1.8V to 3.6V DC. This makes it directly compatible with common 3.3V logic levels found in microcontrollers like ESP32, STM32, and Raspberry Pi, without requiring a level shifter. Ensure your power supply is stable and within this range for optimal performance and sensor longevity.

Does this sensor support both I2C and SPI communication?

Yes, the module features a dual digital interface, supporting both I2C and SPI (Modes 0 and 3) communication protocols. The interface is selected via a dedicated pin (PS). This flexibility allows easy integration with a wide variety of host systems, from Arduino boards using I2C to high-speed SPI connections with industrial PLCs or data loggers.

What is the typical accuracy and resolution of the pressure measurement?

The sensor provides a pressure accuracy of ±1.5 mbar at 25°C across its full 10 to 1300 mbar range. Its high-resolution 24-bit ADC enables a pressure resolution as fine as 0.012 mbar, which translates to an altitude resolution of approximately 10 cm. This high level of precision is suitable for demanding altimetry and environmental monitoring applications.

Is the sensor pre-calibrated, and what is its temperature operating range?

Yes, the MS5803-01BA01 is factory calibrated, with unique calibration coefficients stored in its internal PROM. These coefficients are used by the host microcontroller to compute compensated pressure and temperature values. The sensor is designed for robust operation across an extended industrial temperature range from -40°C to +85°C.
