hi!!

i have been new to the world of sensors!!

i have been using the til 38(emitter) and til 81(detector) pair but the range of this has been very low!!
til 81 is a 2-pin photodiode! the range i have been getting is around 8 cms!! can anybody suggest anything for increasing their range!!
or if anybody could suggest any other gud range sensors.....
i need a range of around 70-80 cms..
plzzz help.

thanx.....

below is the link to til38 and til81 datasheet!!

This is a stupid question to ask , hence no one seemed to reply.
Even if you did a little reasearch u would have known about TSOP's .

Anyhow here you go -
