Soil moisture sensor is also known as: soil moisture sensor, soil moisture sensor, soil water content sensor. It is mainly used to measure soil volume water content, do soil moisture monitoring and agricultural irrigation and forestry protection.

大多数滑坡现象是由强降雨引起的，降雨的入渗是滑坡的主要原因。在此基础上，滑坡监测设备尝试通过添加土壤湿度传感器，实时监测山体土壤湿度的变化。

土壤墒情监测站与传统土壤监测仪器相比有很大的优势，它可以实现每天24小时实时监测土壤墒情，让每一秒关注土壤墒情的变化，并且不需要人员看守，还可以将数据传输到平台，实现多点水分监测，而这些都是许多土壤水分监测仪器所不具备的。土壤墒情监测站结合当地实际情况，特别注重监测数据与作物物候的比较，修正这一评价指标体系，从而更加适合地区和作物，建立土壤墒情和干旱评价全县不同农作物的指标体系。通过分析获得的数据为···

土壤湿度监测系统可以扩展多个传感器，监测更多的环境信息，如土壤水势、紫外线辐射、光照强度、大气湿度、风速和风向等。仪器采用太阳能电池板充电，无论阴天还是晴天都能正常工作，非常适合放置在野外长期监测土壤水分状况。

目前常用的土壤湿度传感器有FDR型和TDR型，即频域型和时域型。目前比较流行的是FDR型，FDR频域反射仪是一种用于测量土壤水分的仪器，它具有简单安全、快速准确、定点连续、自动化、量程宽、校准少等优点。

Soil Moisture Sensor Wide application: small impact of soil texture, wide application area, to achieve low-cost application program.

Through the research on three kinds of soil moisture sensors, it can be seen that the capacitive soil moisture sensor is composed of interdigitated aluminum strips to form the electrodes of the capacitor, and uses air as the dielectric of the capacitor. The capacitance value will also change, so the capacitor can be used as a soil moisture sensor;

Humidity sensors can be generally divided into capacitive, resistive, ion sensitive, light intensity, and surface acoustic wave types according to their measurement principles.

Regarding the common types of soil moisture sensor liquid level sensors, the main methods for measuring soil moisture on the market currently include neutron attenuation method, tensiometer moisture measurement method, and dielectric method speed measurement method.

土壤温度传感器按界面类型区分。当然，由于某些行业的传感器需要以某些特征形式与终端设备交换数据，因此前后出现了几种接口方法。RS485串口类型;2 . RS232串行输出;3 .通用网线接口输出;USB输出方式;
