Measurement Specialties' MS5805-02BA is optimized for altimeters and variometers with an altitude resolution of 20 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.
