the IR interfacing shown below gives the analog o/p and so for that there can be two ways to IR sensor with interface 8051

 either this analog o/p can be given to ADC and then it is interfaced with 8051. this par is expalined on site. go for the link

  or to convert its analog o/p to ttl logic use opamp ion compartor mode….

 

see the comparator ckt below… and for your application it will be more easier, less complex and cost effictive
