Wouldn't it be much more convenient if plants could express their needs by interacting with you? That exactly what the Pet Plant by Junyi Heo does.
The stylish, hi-tech pot measures temperature, humidity, soil conditions and water needs. The measurements are used to make calculations according to the type of plant and its specific needs. Its requirements are then conveniently expressed via pictograms on an LCD display. Also, if you put too much water in, it will automatically drain the soil into a water vessel.
A USB interface is used for charging the pot and for transferring the information to and from the software.
