Hot selling miniature water depth and pressure sensor MS5803-01BA brand new original stock quality assurance

Product Descriptions

The MS5803-01BA is a new generation of high resolution altimeter sensors from TE Connectivity with SPI and I2C bus interface. The MS5803-

01BA HE is the high endurance pad technology version of the MS5803-01BA pressure sensor module. 

It is optimized for altimeters and variometers with an altitude resolution of 10 cm. The sensor module includes a high linearity pressure sensor 

and an ultra-low power 24 bit ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital 24 Bit pressure and temperature 

value 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 any additional sensor. The MS5803-01BA can be 

interfaced to virtually any microcontroller. 

The communication protocol is simple, without the need of programming internal registers in the device. The gel protection and antimagnetic 

stainless steel cap allows the use in 100m water resistant altimeter/compass watches. 

This new sensor module generation is based on leading MEMS technology and latest benefits from TE proven experience and know-how in 

high volume manufacturing of altimeter modules, which have been widely used for over a decade. The sensing principle employed leads to very 

low hysteresis and high stability of both pressure and temperature signal.
