Hello,
I want to ask if there is an analog IR sensor, I tried the receiver module but it it's digital one so it gives 6 v or zero v and doesn't change with distance. I thought of a photo transistor but the problem is that it receives all the visible range too not only the IR
so Is there any Ideas?
For short range robot sensors you can use the 38KHz modules, sending different power pulses out and checking for a return, but it's obviously pretty crude.
