I'm living on a building where in the coridor there is a motion sensor on the wall who will turn on the light when it's detect you. it's way to far from our entrance door and don't detect us when we go out and it's dark. (we really need to be close)
I'm looking for an idea to trigger the light to turn on ...
Of course there is no way to touch the building detector itself ...
it's a solution that I can activate with a buton is ok, when I open the door is better...
Could be old and the collector plastic being with small cracks and can't receive as it was new.
I had that kind of problem in a really old outside parcking light which had more than 4 years under rain..etc
and the plastic was so cracked that couldn't filter/pass thru it anything.
It could be the actual angle degree the motion sensor is not able to reach your door because of the small angle.
If want to try to trigger the IR motion sensor you need a thermal body or object (doing a small research):
found out that to activate a motion sensor you need object that will heat up in between 40~70C degrees and it gonna emitte (more than the usual human body) "10µm to 14µm ++ wavelength range" and it gonna trigger the motion sensor.
Maybe if you put an IR LED on something like your keychain that you take with you everytime, you could point it at the sensor and trigger it from a greater distance.

IR leds come up in between 800nm~950~1000nm if I'm not wrong. What you need to trigger the IR motion sensor you need 5µm ~ 15µm in wavelength.
It's like telling I want to buy a L t-shirt and they give you a XLL one and they tell you it's the same but it's
not the same it's bigger than what you need.
what will be cool is a led who turn on when I open the door in fact ... I need to look if I find a site who sell the proper model
There is no such leds omg dude sry but do you even science?
To turn on the motion sensor you need body heat, every human body that heat's up emitte IR really low radiation (light, not visible for the human eye) there is no such led to do that, you need another body like a metal plate to heat it up at 50~70 degrees C` to trigger the IR motion sensor.
Are there any power outlets in the hall, closer to the door? If so you can put in a motion-activated night light with a brighter bulb. That would provide some light at the dark end of the hall until you were close enough to the sensor for the building lights to turn on.

So to remotely and quickly have something like a metal plate reach 50-70° that look difficult for me.
Or a better idea i would suggest, i wanted it to be my project but now it can be yours too if u like it:
Add a 40w light bulb connected to 220v out of your door using a relay, arduino and a radio transmiter like
the car type, using it like that you can light up (ON/OFF) your own light any time you need.
I had this as one of my projects but moved house and no needed anymore of that
omg dude sry but do you even science?
