This is a firmware application written in C++ using Arduino and Adafruit libraries. It sleeps in low power mode until, activated by the motion sensor, it takes a picture.

Most of us would probably expect to see a PIR sensor, but this light is motion sensing with microwaves. We have seen such units tested in the past, which links to a video [hclxing] also references.

You'll definitely need some gear for it—the Arduino for one, but also a PIR motion sensor, not to mention the (cleaned and rinsed!) Raid Power Sprayer motorized spray bottle.
