Interactive Telecommunications Researchers Develop a Device For Plants to Send Text Messages

January 1, 2009

Interactive telecommunications researchers designed a soil-moisture sensor device that can allow a house plant to communicate with its owner. The device can send short messages to a mobile phone or, by using a service called Twitter, it can send short messages to the Internet. The messages can range from reminders to water the plant, a thank you or a warning that you over- or under-watered it. To communicate, probes in the soil emit electric waves. A voltage level based on the moisture content is sent through two wires to a circuit board that compares the optimum moisture level with the current one. A local network receives this data and allows the plant to send a message through the device.

WHAT IS IT? Botanicalls provides a method for plants to indicate when they need care. Sensors are placed in the soil with a plant, where it measures the level of moisture. The sensors send a signal to a microcontroller, which determines when moisture is low or when water has been added. Then it can send a wireless signal to an internet-connected computer that can send a prerecorded message to the owner. These messages might include a thank-you when plants are watered, or a warning if the watering is too much.

HOUSE PLANTS BENEFIT AIR QUALITY: It may not be an obvious benefit, but house plants can help improve the air quality inside homes. In addition to absorbing carbon dioxide, plants can absorb gases such as benzene, formaldehyde, and trichloroethylene. As builders construct more energy efficient homes, the improved insulation limits the exchange of air with the outside, keeping heat, and some pollutants inside. Many common houseplants that are used to add a bit of life to home interiors will also benefit residents by cleaning up the air they breathe, such as spider plants, peace lilies, and weeping fig.
