Trying to pair a PIR with an Xbee Shield using IEEE 802.15.4?


Im working on this college project to enhance the security features of a Bio-metric scanning safe. My biggest concern is I am using an Arduino 101 with an Xbee Shield v1.3 and an XB24 Series 2 Module. And I am trying to pair the Xbee with this Passive IR I bought that is compatible with the IEEE 802.15.4, Does anyone know how i can get these to pair together via Wifi?

Please and Thanks!
