Adding motion sensor to Existing Lights that are already controlled by a dimmer?

Hello,
I have my porch light controlled by a dimmer; however, I would like to add a motion sensor with the end result being that the light attains full brightness when the sensor relay is triggered. Can anyone recommend how this could be wired or if it is even possible? Thanks for any advice!

I'm not sure if you can make that happen by adding a motion sensor to a light that is controlled by an ordinary dimmer switch.
However, there are lights that can function somewhat in the way you want.
They are called "Dual Brite" lights. (I think that is a trademark name, mine were manufactured by Heath Zenith.)
They can be set to come on at dusk, at half brightness, and go to full brightness when the motion sensor ... um ... senses motion. They shut off at sunrise.
I installed 3 of these on my house about 8 months ago, and so far, so good.
This would require new lights, as opposed to just a new motion sensor.
[As I'm not sure how proper adding a link would be, if you Google "Dual Brite", you will see a bunch of links to info about these.]

Having just reread this post, I recall seeing "retrofit motion detectors" advertised somewhere...maybe they have one that can create the "dual brite" effect on an existing light.
Good luck with your project.

If you would install a diode between the red and black on a motion sensor, you would always be at low and when the sensor kicks on you would then be at high.
