The choice of the add-on motion sensor especially. Need nearly a
180-degree sensitivity and a great service-life profile.
I've been using these:

The sensing angle is about 100 degrees but you do get six of them along
with mounting brackets. Also the output is digital not analog. There are a
number of other options but I think the all use the same sensor. It's
adjustable for range and sensitivity.
https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/overview
has information on how they work and some of the adjustments. The ones I
have are very close to Adafruit's new design. Follow the pages and there
is a simple diagram with batteries, the module, and a LED, no Arduino. You
could do something like that but drive a FET to control the main LED.
