Application of Soil Moisture Sensor in Agricultural Irrigation

Agricultural irrigation mainly refers to irrigation operations in farming areas. Agricultural irrigation can be divided into traditional ground irrigation, ordinary sprinkler irrigation and micro-irrigation. 

The traditional surface water irrigation includes side irrigation, furrow irrigation, flood irrigation and flood irrigation, but this kind of irrigation is often an unreasonable agricultural irrigation due to its high water consumption and low water consumption. In addition, ordinary sprinkler irrigation technology is a more common irrigation method in agricultural production. However, common sprinkler irrigation techniques are not very water efficient. 

Modern agricultural micro-irrigation technologies include micro-sprinkler irrigation, drip irrigation, infiltration irrigation, etc. Compared with traditional irrigation methods, these irrigation technologies generally have better water-saving effect and higher water utilization rate.

Whether it is traditional irrigation, normal irrigation or micro-irrigation, we cannot judge by the naked eye whether the humidity of the land has reached the optimum humidity required by the crops. At this time, we need a soil moisture sensor to help us monitor the moisture of the soil to ensure that the soil reaches the optimum humidity for plant growth after irrigation.

Soil moisture sensor is a sensor that monitors soil moisture, and can also be called: soil moisture sensor, soil moisture sensor, soil moisture sensor.

Mainly used to measure soil volumetric water content, used in soil moisture monitoring and agricultural irrigation and forestry protection. The probe of the sensor is buried to the depth required for moisture monitoring to monitor soil moisture. By measuring the dielectric constant of the soil, the volume percentage of soil moisture is measured and uploaded to the monitoring platform in real time.

 If the humidity is too high, the irrigation will be stopped; if the humidity is too low, the irrigation can be continued through the photoelectric isolation and relay control of the solenoid valve connected to the water source.

The monitoring platform also has an alarm function, which can set the upper and lower limits of humidity. When the humidity is too high or too low, it can be notified in time through the platform interface alarm, SMS alarm, sound and light alarm, etc.

In addition to monitoring the operating status of the system in real time, the platform can also record and analyze historical data, as well as download and print data, which is convenient for scientific research.
