This uses a RCWL-0516 radar module to control a strip of 30 white LEDs.
It seemed like a good night light, and we first used it in the bedroom. It was unsatisfactory because we could not confine its operation to persons standing. It would operate unexpectably while we were asleep.
Next we moved it to the bathroom. It worked OK, but did not stay on long enough unless the person waved or figeted, despite adding capacitors to the output.
These are photos of the device.
