hi everybody,
i build this ir based proximity sensor...
all the components are on the same plane, so the IR receiver will only receive IR that is reflected on an object in front or the board..
But the results are not exactly what i expect, the range is really low: only 4 to 5 cm in best conditions!!!
it is strange because i am using 8 IR leds... i dont know weather i have an error in the following circuit or it is impossible to do..?
here is the circuit..
