The Internet Sprinkler Controllers have an advanced way to attach to sensors. Most sensors close or open a switch. These are called switch closure sensors. You may also have heard the term ground interrupt, which is another way of saying the same thing. While Ware Engineering does not currently produce any sensors products there are a wide variety of sensors to choose from.
Connecting sensors directly to the controller has the advantage of allowing the controller to determine how to respond to the sensor's input. For example, a wind sensor connected in the old style would prevent the water from being wasted but the lawn may burn because of insufficient water.
Benefits of having the sensors measurable by the controller
In addition to regular sensor functions a sensor can send X10 commands. This could be used to turn on a light using a vehicle motor sensor, breaking glass sensor, or Door opening sensor. Since the most effective theft deterrent is light this could enhance security.

The Internet Sprinkler 1016 Controller does not have sensor input and so this is the only way to connect a sensor. This works fine but you loose some functionality.
Browse the software on an actual Internet Sprinkler Controller on the Internet: The software consists of 7 web pages that contain scheduling information and a wide range of other features. It is stored on the timer in flash memory (this means it will not lose its information, even with total power loss). The timer has its own web server to allow you to access the software as a web page from your computer, over a network, or even on the Internet by customizing the IP address.
