The circuit the transmitter.
Long range ir beam break detector circuit.
One reader asked how to use my arduino infrared library to detect breakage of an ir beam.
I m using your circuit as my project for my final year project.

The answer was too long for the comments section so i ve extended into a blog post.
The first mode is beam break triggering.
Beam break detector for era shutter or flash control.
The range of the long distance ir beam break detector easily reached 7 meter using a single ir led driven with about 10 ma which is well below the maximum current.
A cheap beam break sensor utilising a reflector panel instead of a transmitter receiver setup.
One straightforward way is to use the library to modulate an ir led at 38khz and use a standard ir detector module to detect the signal.
Long range beam break sensor with reflector panel.
I have questions regarding to your long range ir beam break detector circuit.
The long range infra red beam sensor.

Ep 07 beam break sensor duration.
In this mode the beam is normally detected by the receiver and is interrupted by an object that passes in front of it.
Because people keep asking me for a long range ir beam break detector i made this circuit which has a range of nearly 10 meters 33 feet with only a single high power led using no lenses.

Robots with the rockettes.
When it transmit the receiver starts to blinking.
Capable of handling long distances.
I m using a regular ir led.
I have a little problem with the transmitter.
When you need a longer range you can add extra ir leds.
