This barometric pressure sensor 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 MS5611-01BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need  of  programming  internal  registers  in the device. Small dimensions of only 5.0 mm x 3.0 mm and a height of only 1.0 mm allow for integration in mobile devices. This new sensor module generation  is  based  on  leading MEMS  technology and  latest benefits  from MEAS  Switzerland  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.
