Absolute Xtrinsic Smart Pressure SensorFrom Freescale:Freescale's Xtrinsic MPL3115A2 provides highly precise pressure and altitude data with variable sampling rate capability. It has very low-power consumption, smart features and requires zero data processing for mobile devices, medical and security applications.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.Features Less than 1 foot / 0.3 m resolution Pressure range: 20 – 110 kPa Compensated, direct reading (software is not needed): 20-bit pressure measurement (Pascals) 20-bit altitude measurement (meters) 12-bit temperature measurement On-board intelligence Flexible sampling rate up to 128 Hz
