基于土壤湿度检测的滴灌控制器设计与研究

摘要

Drip irrigation control er designed in this paper is mainly composes of single chip,soil moisture detection and electro-magnetic valve drive circuit and other units.YL-69 soil humidity sensors to detect the soil humidity information,based on in-termittent irrigation and dejitter anti-interference algorithms,ensures the accuracy of the soil humidity information,and through the single chip could control the start and stop effectively,then adapted to the suitable soil humidity.%设计的滴灌控制器主要由单片机、土壤湿度检测和电磁阀驱动电路等单元组成。利用YL－69土壤湿度传感器检测土壤的湿度信息，采用间歇滴灌和去抖动防干扰算法，保证土壤湿度信息的准确性，通过单片机有效控制滴灌电磁阀的开启与停止，以保持土壤合适的湿度需要。
