The Giz Wiz is back with the strangest gadget of 2012 ... the Koubachi Wi-Fi Plant Sensor, which makes your plants wifi enabled! What it does is send you notification that your plant needs water or attention. The sensor learns the watering cycle of your plant and then will remind you to no matter where you are. It remembers up to 27 different plants, so you can move them from plant to plant. For indoor plants it's $99, and the outdoor version $129. It may just be cheaper to buy a new plant when the old one dies.
