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