基于土壤墒情的节水灌溉控制器研制

Development of Soil Moisture-based Water-saving Irrigation Controller

根据目前主要应用的土壤湿度测定方法和传感器的优缺点,选择TS-4陶土头土壤湿度传感器进行标定,并基于土壤墒情的一种灌溉控制器。该控制器具备土壤湿度控制灌溉模式、时钟控制灌溉模式、频繁间歇控制灌溉模式,并具有操作方便、节水效果好、宜于推广的特点。

According to the advantages and disadvantages of the main methods of soil moisture determination and of the sensor,it selected the soil moisture sensor of TS-4 clay to be calibrated,and a soil moisture-based irrigation controller was designed.The controller was equipped with soil moisture control irrigation mode,the clock control irrigation pattern,frequent intermittent irrigation mode,which was easy to operate and promote,as well as effective to save water.
