Multiple PIR motion sensors to same pin

I am wondering if it is ok to wire multiple PIR motion sensor outputs together to the same pin on something like the Arduino. I simply want to see if there is motion from any of the sensors.

Though it is technically possible, putting them through an or gate is a much more reliable and stable approach to the problem. There are other methods as well, but I would generally advise against simply tying the outputs together for anything other than playing around.
