摘要
本控制器采用一个检测电极插在苗圃中，对蒸发进行采样。当上壤干燥到一定程度需要喷灌时，检测电极会反馈一个信号给控制器，起动水泵喷灌，可避免作物干死，有利于大面积的作物栽培。
This controller take samples from vapor by means of a test electrodesticking in the nursery. As the soil happen to be a certain dryness, it needs to be irrigated.The test electrade will feed a start signal to the controller for irrigation by a pump. Therefore the crops will be safe from dryness. It is good for planting in wide area.
