This was my choice for the motion sensor installation. I discarded the dome
lens so that I could hide the sensor. I drilled all holes in the speaker area of HAL.
Placing the sensor behind one of the holes ga e me a motion range of about 4ft.
I enlarged one of the holes, shown abo e, gi ing a range of about 10ft. E en
though this hole is larger, when looking at the front of HAL, this hole still blends
in.
This installation limited the annoying acti ation of e ery mo ement in my
office, gi ing me more control of when HAL acti ates. You may also choose to
install the sensor outside the model to use it with the dome if you need more
sensiti ity.
Line up the motion sensor chip, the round protrusion with rectangular
window, centered o er the large hole you drilled. Hot glue it in place. Make sure
the sensor is mounted flat, not angled in one direction or else the sensor will be
more sensiti e to one side than the other. Mine is a bit off but I don't mind it :)
Test the sensiti ity, if it works well for you, add a little more hot-glue.
