Abstract
An automatic water supply system capable of cultivating a plant in a state as proximate to be natural as possible and robustly and capable of eliminating waste of water, which is an automatic water supply system in which at least deficiency of water of an object of water supply is detected by a water content sensor, a first predetermined time period is measured by a first timer portion in accordance with the detection, when sufficiency of water is not detected by the water content sensor within the first predetermined time period, water is supplied by water supply means and when sufficiency of water is detected within the first predetermined time period, the first timer portion is initialized. According to the automatic water supply system, it is preferable that water is stopped from being supplied after elapse of a second predetermined time period measured separately or water is stopped from being supplied when a measured value of a flow rate meter installed at a water path reaches a previously determined flow rate value after starting to supply water.
