<p>A water sprinkling control apparatus with a built-in memory holding a plurality of water sprinkling programs which determine water sprinkling timing for a large number of water sprinkling stations. It is possible to determine an optimum water sprinkling schedule by selecting one of the water sprinkling programs stored in the memory, correcting it if necessary, and combining a water sprinkling time and a water sprinkling date. Each of valve devices in the water sprinkling stations are successively controlled according to the thus-determined water sprinkling schedule, and, if necessary, the water sprinkling schedule is automatically and continuously repeated. The apparatus can be easily operated using a small number of keys and a display, it is compactly housed in a small box with a solar cell acting as a power source, and it can be instaled outdoors.</p> |
