WASHINGTON (Reuters Life!) - Chances are you've never had a conversation with your house plants but if they could talk, what would they say? "Water me."

Researchers at New York University's interactive telecommunications program have come up with a device that allows plants to tell owners when they need water or if they've had too much via the social network blogging service Twitter.

"Obviously plants can't talk or Twitter directly, so we have to help them along with that," said Rob Faludi, co-creator of the device called Botanicalls.

The device is made of soil-moisture sensors that are connected to a circuit board. They measure the level of moisture, and then communicate the information to a microcontroller.

"There are settings in the software that allow you to set what kind of plant you're using and also adjust for characteristics of the soil, different soil has different qualities," said Faludi.

The device determines whether moisture levels are too low, or too high, and then transmits a wireless signal to Twitter, via the Internet, which lets people send short, 140-character text messages to their network of friends.

Botanicalls co-creator Kate Hartman said the language used in the Twitter messages can be personalized to suit the owner, or the type of plant.

"There's always a basic "I'm thirsty, could you please water me" message. But they also accelerate in terms of need, so there's an urgent message: "I'm desperately thirsty, please water me,"" Hartman told Reuters.   Continued...
