  • 摘要:温室大棚土壤环境参数影响作物正常生长,需长期对其进行监测。针对现有固定式温室大棚土壤参数监测仪中传感器末端普遍长期埋于土壤中,导致传感器使用寿命缩短的问题,引入一种基于Arduino的土壤参数监测仪。该仪器可实现对土壤参数的定时检测,为植物生长所需土壤营养成分的配比和定时灌溉提供实时精准参考数据。在数据采集完成后实现对监测仪传感器探针部位的自动清洁和维护,减缓了传感器因长时间接触土壤造成的电化学腐蚀生锈,提高了传感器使用寿命。该监测仪为实现智能化温室环境动态监控物联网系统的开发奠定了一定基础。

  • Abstract:Normal growth of crops was affected by soil environmental parameters of greenhouse.Therefore,it needs to be monitored for a long time.For existing fixed greenhouse soil parameter monitor,sensor ends are widely buried in soil for a long time,which leads to shorter service life of sensor.A soil parameter monitor based on Arduino was introduced.Instrument could be used to detect soil parameters regularly.It provided real-time and accurate reference data for ratio of soil nutrients required for plant growth and time irrigation.After data acquisition was completed,probe position of sensor was automatically cleaned and maintained. Electrochemical corrosion caused by long time contact with soil was slowed down,and service life of sensor was improved.This monitor lays a foundation for development of intelligent network system for intelligent greenhouse environment monitoring.
