sumo sensor

[ccdjr106]

hello, im looking for a sensor to keep my mini sumo robot from going out of the ring.  Im looking at this one http://www.trossenrobotics.com/p/phidgets-IR-relfective-sensor-5mm.aspx but i dont know how easy it would be to use with the arduino.  If anybody knows how to use this sensor with the arduino I would appreciate the help.

I want to enter the national robotics challenge mini sumo competition http://www.nationalroboticschallenge.org/.  This it the second robot that ive built.

thanks in advance

That *Should* work as long as its a regular interface. If its made specifically for phidgets only then it wont work easily.

Seems a bit expensive considering you can get this:

But the look like they have 4 pins so how would i use them

Apply 5v to the emitter side and detector side and hook pin 3 up to an i/o pin.
