Mother Smart Sensor System
A sensor for this, a sensor for that — it's obvious that we're going to have a lot of sensors in our lives from now on. Instead of trying to wrangle a bunch of single-purpose gadgets, let the Mother Smart Sensor System take care of things. This system includes an Internet-connected "Mother" base station and a set of four sensors that can be used in a variety of ways: they can sense movement, letting you know when something has been moved, as well as temperature and proximity — since they signal their presence to the Mother, you'll know when they're coming or going. Stick them on whatever you want, set them to sense what you want, add more of them as you need them, and let the Mother keep track.
