Yes the IR Detector used in Tv sets should work fine. The detector is TSOP 1738. I have done a project using this sensor. It costs near about Rs 25 a piece .

tsop 1738 needs modulated signal.....
u can use ir receiver which is simply like a led...
go to ay troniks shop and ask for the emitter/receiver pair.. they ll give u tat and ll tell u which one is wat.
