    Hi All,

    I have a horizontal MEAS vibration sensor set up to my analogue input at the moment which lights a digital LED when vibrations over a certain threshold are detected. I now want to expand this project further in to allowing the arduino UNO to wake upon a vibration and light the LED giving better battery consumption.

    I have read that the arduino wake libraries via interrupts require digital and not analogue inputs so I assume I would need to use a comparator to interface to digital.

    Does anyone have any example circuits showing how this could be done? The sensor is here:
