Beam Break Sensor

I am a college student doing hobby project, I need to design an IR bream break detector which would work with IR Transmitter and IR Receiver to detect beam break between transmitter and receiver in 1 meter range. Can you please suggest components and circuits for same, preferably requiring 5V. The functionality should not get affected in ambient lighting as well. I will be connecting this to Arduino MC

One normally thinks of use Arduino to measure the V out at receive end of the
detector, analog detector. Of course design complicated by ambient light issues
interfering in detector output.

There are lots of articles available using a 38kHz receiver module with an Arduino. One example.
It sounds like you need to generate the signal with another circuit as the AGC on the reciever modules mean they have to have a pulsing signal (500mS as well as 38kHz).

You could easily get started with just a module, an Arduino and any remote.

Note, television remotes all work at over a meter distance.
