摘　　要：住宅小区及商业环境中,植被覆盖率高,当前一般采用定时、定量的浇灌模式。当前的草坪灌溉系统多采用定时器进行定时浇灌,每次灌溉用水量基本相同,但植被在夏冬季节需水量差异较大,且在雨天一般不需要重复灌溉,利用定时器进行浇水控制是不尽合理的。随着传感器技术的发展,利用传感器对土壤干湿度进行监测,通过对土壤湿度阈值进行动态判定并驱动电磁阀开闸浇灌,能有效节省水资源。In the residential area and commercial environment, with high degree of vegetation coverage, the regular and quantitative irrigation mode is generally adopted at present. The current lawn irrigation systems often use timers for regular irrigation, and the amount of water used for each irrigation is basically the same, but the water demand of vegetation varies greatly in summer and winter, and there is generally no need for repeated irrigation in rainy days. It is unreasonable to use timer to control irrigation. With the development of sensor technology, the use of sensors to monitor soil dry humidity can effectively save water resources by dynamically determining the soil moisture threshold and driving the solenoid valve to open the gate for irrigation.
