NXP MPL3115A2 Altimeter

Freescale's Xtrinsic MPL3115A2 provides highly precise pressure and altitude data with variable sampling rate capability. It has very low-power consumption, smart features for mobile devices, medical and security applications

Hello World

Import programWIGO_MPL3115A2

Demo program for the MPL3115A2 library.


Import libraryMPL3115A2

Llibrary for the WiGo MPL3115A2, I2C Precision Altimeter sensor.




The Xtrinsic MPL3115A2 pressure sensor smart features include digital output, two interrupts for auto-wake, minimum/maximum threshold detection and autonomous data acquisition. MCU usage can be limited since the MPL3115A2 pressure sensor can process sensor data locally, reducing communications required with the host processor.
