Altitude/Pressure Sensor Breakout - altitude and pressure measurement module with MPL3115A2

Description

Atmospheric pressure sensor module with altitude and temperature measurement function based on the MEMS MPL3115A2 sensor. It has the ability to program events and sampling frequency (in the range from 1s to 9h). The MPL3115A2 sensor is fully internally compensated. It provides height data with an accuracy of 30 cm. The sensor outputs are converted by a high resolution 24 bit ADC and sent over I2C.
