Possible to reuse 2gig motion sensors?

Hi! My husband and I moved into a house in October, and recently joined the crazy world of home automation. The previous owners of our house left behind two 2gig motion sensors - these ones http://www.smarthome.com/2gig-technologies-2gig-pir1-345-pir-motion-detector.html - and I’m wondering if there’s any way I can repurpose them to connect to SmartThings. My Google skills are failing me on this.
Thanks!
