This is not well thought out.

What is 2 go in and 1 comes out?
If no sensor , what is the input if you forgot?

No sensor? Hire a light-switch attendant.

Normally motion sensor is needed with delay timer shutoff and fast turn on.
PIR sensors are slow turn on. IR sensors are fast turn on.

you may use a reed switch as a sensor programmed on arduino microcontroller .
