http://kbase.x10.com/wiki/Comparison_of_All_Motion_SensorsTo sum up Jim's link and give me a lot of practice using the table feature here...

...You obviously have too much free time. ;D ;D...Yeah. I've had a bunch of free time. I fell from a latter about 15 ft to the driveway last Fall while putting up the Christmas lights. Left me pretty banged up for awhile. I go back to work next Thursday so I won't have as much time to be creative here. This board has helped me from getting too board in the meantime.
...It took me all of 10 minutes to loose the rubber plug on the MS16...Mine is mounted horizontally under the porch overhang so I decided not to worry about the plug. I suppose I could hit it with a drop of hot glue if it really mattered.
I always use this chart because it's more complete (and possibly accurate):Yes this is a much more complete description. I won't try to summarize it here. ;)Comparison of X10 Motion Sensors (http://www.activehomepro.com/sensors_compare.htm)
