InfraRed With PC Interface

Hello to all

i am looking for a infrared security device

like we see the counting system and in the doors will automatically open when person is entering so that i can install int he system if anyperson comes infront of the system so that i can write the program to execute another application
or give the messgae to move infront of the system

infrared is installed in a kiosk. when someone is infront of the infrared beam the software should detect the beam interruption, it should detect that someone is infront of the kiosk and raise an event...
so that it can handle from the PC and can execute the software appropriately

eagerly waiting for the replyies

thank u

Don't you think in using a microcontroller to do it? or you really mean to interface with PC?

If you want to use PC interface, there're many IR Rx circuits to interface w/ PC via UART interface,

Here's one: http://lnx.manoweb.com/lirc/

For the Software, you will find in the link above another links to many Softwares that you can easily use....

I hope that helps,
