Absolute pressure sensor MS5803
The MS5803-xxBA is a new generation of high-resolution sensors with SPI & I²C interface. The sensor module includes a high-linearity pressure sensor with an ultra-low power 24-bit ADC with internal factory-calibrated coefficients. It provides precise digital 24-bit pressure and temperature values and different operation modes that allow the user to optimize for conversion speed and current consumption. A high-resolution temperature output allows the implementation of an altimeter/thermometer function without an additional sensor. Gel protection and an antimagnetic stainless steel cap allow the use in 100m waterproof altimeter/compass watches.
The MS5803 is available in the following pressure ranges:
- MS5803-01BA: 10-1300 mbar
- MS5803-01BA07: 10-1300 mbar for harsh environments
- MS5803-02BA: 300-2000 mbar
- MS5803-05BA: 0-6 bar
- MS5803-07BA: 0-7 bar (not for new designs)
- MS5803-14BA: 0-14 bar
- MS5803-30BA: 0-30 bar
*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
Accessories for the MS5803
Also available are sample boards, which can be used together with the USB Development Kit to quickly evaluate the sensors and build prototypes, as well as light and dust protection caps.
