Which will be Cost effective

[vinoth]

Hi,
I have three option to use IR sensor for my robotic toy. One is IR transistor and second is Photo diode and third one is Three pin IR receiver. Which will be cost effective. Please suggest me

The first two require lot's of extra circuitry to make them work - the IR receiver is complete in itself.

Depends really what you want to do with them.

Thanks for your reply.IR LED emits signal 36KHz using 555 timer circuit. When any object found I should get the signal from receiver for that I need that.

In which case you need the IR receiver.

I planed to use PNA4602M 38KHz IR receiver. Is this cost effective instead of using IR transistors .

Yes, because you don't have to build all the amplifiers, filters, and demodulators.

Which shows a far superior version to using 555 timers.
