hi,
can i use this simple IR receiver (SN-IR-R) to sense the distance of an object?
basically the task is to emit sound when the object is near. as the object gets closer and closer, the buzzer will beep faster.
i want the ir transmitter and receiver to be separated so that the transmitter can be carry around until it come across the receiver.
does the ir receiver output varies according to the intensity of the IR light?
is that any other better to achieve the above task?
thank you for the reply.
