Default motion sensor switch

i have a couple single pole switches for which i'd like to have a motion
sensor switch instead. the current switches have two wires connected: a hot
coming into the bottom and then the switched hot going out of the top to the
light bulb. when i looked around at the motion sensing switches it has four
wires (black, red [for the load], white and green) and says it requires a
neutral. i've never come across a switch that has a neutral hooked up to it.
what am i missing here?
