The system uses 40 wireless units on existing trellising posts around the 30-acre vineyard fitted with sensors that measure microclimate data such as soil and air temperature and moisture content, rainfall and leaf wetness. The data is bounced from sensor to sensor sans wires, forming what is known as a Mobile Ad-hoc Network (MANET), which requires less power and equipment than networks using wires or radio transmitters.
Real-time conditions in the vineyard can then be monitored on a secured Web site. Data can also be poured into a spreadsheet for long-term analysis. The information can help vineyard managers make decisions about when, where and how much to water vines or spray to control mildew.
The system sends alarms via instant messaging software or cellphone. The article quotes Bill Westerman, who works for Calif.-based Accenture Technology Labs which set up the project, as saying that the system could be used in manufacturing, retail and security. “The advantage to wireless is that it allows companies to go places where it was previously too difficult or expensive to run wires,” he said. “It can also be implanted in new products so they can automatically communicate with their manufacturer when there’s a problem.”
