2 wire light switch

I am changing a pull cord light switch to a motion sensor one but after opening the old light switch it only has a black and red wire and the black goes to common on the old pull switch the new sensor has 3 wires how do I wire?

If the third wire that is needed is a neutral---you will need to add a neutral to the box.

Odd set up--pull chain switches are usually part of a light fixture--and a light fixture has a neutral--More info please.
