    Default Electric Garage Door sensors for Halloween use? – 07-06-2009,05:19 AM


    Has anyone used garage door sensors to use for motion sensors for halloween? They seem the best bet and very inexpensive.

    How inexpensive we talking? I've bought retro-reflective break-beam sensors before for rather cheap and those only require 1 sensor and a reflector. My garage door has two sensors, an emitter and a receiver...

    Doesnt the garage door sensor cut power off? I am guessing you'd have to reconfigure that part of it.....

    It not the sensor usually, it's what you want to activate. Those sensors usually need to be connected to a relay (mechanical or solid state) before you connect to something you want to activate, along with power.

    This was discussed briefly in another thread:

    Protect your props from theft with this..

    Apparently the sensors use a Pulse Width Modulated (PWM) signal to communicate back to the opener - so they don't work that great for triggers.
