Under-cabinet LED Strip IR Sensor: Re-aimed

The under-cabinet LED strips work wonderfully well, except that the IR sensor seemed rather hypersensitive, so I added a small reflector made of shiny steel:

Under-cabinet light - IR sensor mirror
Under-cabinet light – IR sensor mirror

Even though I rounded those corners and deburred the edges, it does look a bit threatening, doesn’t it?

It moves the sensor’s hotspot back about half a foot, which seems Good Enough to eliminate false triggering from normal activity over the cutting board.
