Using Wired Sensors with Smartthings

New to all of this so sorry if this has already been asked 20 times:)
Can I use all of my ADT sensors in my house with this system? I think the answer is yes but need to understand what is needed I have 4 door, 2 motion, 2 fire wired sensors. Thanks Troy

Most economical solution is an Arduino and a thing shield. But the thing shields are out of stock right now.

Many of the open/close sensors have inputs for 1 or 2 wired sensors, but that can get pretty pricey for the number of sensors you are looking at.
