LAS VEGAS--This is what Bluetooth was invented for: a tong you stick in the soil of your plant that tells you when to water it.
The Flower Power is a gadget that Parrot will bring to market at some stage this year -- there is no word on price yet while the company works out how much it can get away with charging. The fork has sensors that send the information they pick up from the soil of your plant via Bluetooth to an iPad app.
Once you have told the app what the plant is, it cross-references the information received with the info in its database to tell you which day it needs watering, whether it's getting enough sun, and if it's hot or cold.
You can move the tongs to different plants, and see information on them all on your tablet screen. It also works on lawns.
