TIDM-RF-SENSORNODE: Metal detect sensor

Hai TI,
application:
sensor:
 I need such a sensor which can detect non magnetic and magnetic metal(iron) and a sensor should produce a RAYS which penetrate thought the surface like wood and other surface and detect the object.

laser light:
  when the sensor detect the object the controller should trigger the laser light and the light should fall on  the object.

controller:
  when the  sensor detect the object the controller should trigger and send  the signal to the laser light 

I want metal detect sensor, Is there any wireless protocols will support.
