Hello,
  I have a couple of Sharp GP1U52X IR detector moduals.  I wanted to know
what range of sensitivity I can expect with these units.  They will be
employed for a wall detection system.  I read in the Mobile Robots book
that these types of moduals are sensitive to radiation around 880nm.  My
question is what is the range 879-881nm or 600-1200nm?  If I were to use a
different wavelength then the one specified, would this affect proformance
to a noticiable extent?
