Overview

The The MS5805-02BA sensor 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. This sensor can be interfaced  to virtually  any  microcontroller. The  communication protocol is simple, without the need of programming internal registers in the device. The sensing principle employed leads to very low hysteresis and high stability of  both pressure and temperature signal.
