    I am a Structural Engineering student and I am working on a project using a laser sensor which outputs a voltage between 0 to 10V (depending on displacement measured). However, I need to feed the range into a DAQ board (Data Acquisition) and it requires a range of -5V to 5V. Is this any easy fix with a circuit? Or is it more complicated than it seems? Help please, I don't know much in the way of electronics!

    Data Sheet for Laser also gives:
    -Current Load Voltage Output: < 1 ma
    -Current Output Load Resistance <500 Ohm

    An "easy" fix would be to add a -5V power supply in series with the output of the sensor. That will offset the output to the correct range.
