Opensmart infrared reciver and emitter

Hi, this is my first post on this forum and pretty new with ardunio. I'm looking into to create a tripwire with ir sensors and I have got my hands on NE555 Opensmart sensors.

Anyone know how to hook them up to ardunio and have some simple code for a tripwire? Example, when the tripwire breaks a led lights up.

Thanks in advance! I apalogize if this post is in the wrong section. Regards Peter
