hi to all,
i had designed the through beam sensor by using of the IR transmitter and IR Receiver LED. Its working quite properly. My doubt is how to find the signal strength of the IR tranmsitter Led, without receiver. By the use of receiver i can determine the distance. but not able to find the strength. If i vary the Forward voltage of the IR Transmitter, distance getting increased, while decrease the forward voltage, distance also getting reduced.
Kindly tell me how to determine the strength of the TRANSMITTER?
Thanks in advance,
