MPL3115A2

板机接口压力传感器 I 2 C VERSION  I2C precision pressure sensor with altimetry

General description  

The MPL3115A2 is a compact, piezoresistive, absolute pressure sensor with an I2C  digital interface. MPL3115A2 has a wide operating range of 20 kPa to 110 kPa, a range  that covers all surface elevations on earth. The MEMS is temperature compensated  utilizing an on-chip temperature sensor. The pressure and temperature data is fed into  a high resolution ADC to provide fully compensated and digitized outputs for pressure  in Pascals and temperature in °C. The compensated pressure output can then be  converted to altitude, utilizing the formula stated in Section 9.1.3 "Pressure/altitude"  provided in meters.The internal processing in MPL3115A2 removes compensation and  unit conversion load from the system MCU, simplifying system design.
