Here are some benefits that MPL3115A2 can offer: Sensing readout from MPL3115A2 is fully internally compensated and no software is required, achieves high accuracy without the resources from an MCU to do all the calculation and feedback, which also saves on power consumption and the option to choose the output data rate. With internal FIFO, output data rate (OSR) will be 1Hz and if the user decides to use one shot mode (OST) the output data rate can be up to 128Hz.
