MPL3115A2 Overview

The MPL3115A2 is a low-cost, low power, highly accurate barometric

pressure sensor. Use this sensor to detect changes in barometric pressure

(weather changes) or for altitude (UAV controllers and the like). The sensor

is very sensitive and capable of detecting a change of only 0.05kPa which

equates to a 0.3m change in altitude.

Things you should know about this sensor:

• Uses the I C interface

• Only one sensor can reside on the I C bus

• Uses the I C repeated start condition. Arduino supports this, check if

you’re using a different microcontroller.
