Abstract
Now you are going to take a look at pressure sensors, in particular, the MPL3115A2 digital pressure sensor from Freescale. This is a great sensor that is easily interfaced with an Arduino and provides accurate pressure and temperature readings. The device needs to be connected to the Arduino’s I2C (inter-integrated circuit or I-Squared-C, also known as a two-wire interface (TWI)) bus for data to be exchanged. I2C is a new concept for you, and although this chapter will not cover it in great detail, you will learn the basic concepts of the I2C and how to use it to get data from the MPL3115A2 sensor.
