The well-made Greener Lawn system gathers historical weather data and forecasts and then makes intelligent watering decisions based on that data. The design features an ATmega128 processor connected to the Internet through a WIZnet WIZ810MJ. The weather forecasting and rainfall totals come from the National Weather Service’s FTP server. Linux shell and Perl scripts gather the data and parse out the rainfall totals. This is stored as plain text files on the Linux web server. A PHP script running on an Apache web server enables you to configure the sprinkler controller. A second PHP script ties all of this information together into a single downloadable file that is requested by the WIZ810MJ. |
