We've got flowers that have seen fire, and now we're seeing ones that brave the rain, as Asahi Kasei's plainly-named Rain Sensor spends (quite literally) half its time perched outdoors awaiting those sprinkles. As you might expect, this two-part device consists of a mountable rain sensor that resides outside and connects wirelessly to the indoor monitor in order to alert you when it begins to drizzle. Presumably aimed at those who frequently leave their car windows down or wet clothes on the line, this little fella belts out a friendly jingle whenever its drop-sensing partner feels the water. Although there's always the "look out the window" approach, this device does indeed save you from focusing intently on what's happening outside in order to determine precisely when the first drop falls, but even if it doesn't seem worth the ¥3,980 ($33) asking price to you, be sure to click on through for a live demonstration anyway.
