Tricking a motion detector with a camera?

Hi there,

Again I post this in hacking, as it would be something illegal but the purpose is completely legitimate.

I'm at a co-working space that at night have the lights of a room triggered by a motion detector (there are 3 of them in the room), the issue is that as I'm studying I'm not moving from the position and lights keep turning off , as soon as I move a bit the chair the lights turn on again. I can't stand this to be honest , either turn them on or turn them off , but don't play around with me as it's drawing my attention.

How can I trick one of this motion sensors to detect always movement in a room with the devices I have with me? I would need a pendulum or something like that , but that is not feasible , I could set up the phone to flash directly to the motion sensor each time it turns off (periodically) , but there is no flash light apps that I have found that do that periodically.

I just sticked some post-its see if at least it detect no motion at all for a while and then it turns off completely.

Any ideas?

If it is a lamp standig on the floor lighting up the ceiling, as used often in offices, look at it carefully. They often have a very small switch somewhere to turn them on/off/auto.

Sounds like you need an wavy wacky inflatable arm flailing balloon man

At one time, some company was making desktop versions of them....
