The Rain8PC is a 8 zone irrigation controller that connects to the serial port of a computer.
San Antonio, TX - August 2003 WGL and Associates announced today the immediate availability of a RS232 based irrigation controller. This new device enables most computers to control all aspects of an irrigation control system.
WGL and Associates is pleased to announce the addition of the Rain8PC to their line of sprinkler controllers. This new product was designed for use in residential, or commercial irrigation. Conventional irrigation controllers contain a very limited means for the user to specify how and when irrigation is desired. Their small LCD display and limited keypads make complex irrigation scheduling very difficult, if not impossible. By using a computer with its large display and full size keyboard, complicated schedules are very easy to implement.
An additional benefit once you have the computing power of a modern PC, it is easy to create "if..then" logic conditions. This in turn conserves on a rapidly dwindling resource, our water. By programming in variables such as Evapotranspiration it is possible stretch to the maximum this precious resource. Included in these calculations are wind speed, humidity, air temperature, solar radiation and ground temperature. Without the power of a computer these calculations are hard to make.
WGL and Associates was founded in 1992 to provide engineering assistance to a number of manufactures. In 2002 the first home automation products were launched to fill a demonstrated need in the market.
