Following my earlier entry on the likes of dubious brands e.g. Toceba Batteries. I chanced upon this one when I was in the toilet of the DongGuan Hillview Golf Club where I was having a tournament (more on that in a later entry).
There I was taking a leak when out of boredom, I started to look around (while stuck to the urinal for obvious reason) and eventually my sight landed on this.
That is the infrared sensor which is part of the auto-toilet-flushing system.
