Soil moisture monitoring system to keep the pulse of soil health
Soil is the surface of the earth's land composed of minerals, organic matter, water, air and living things. Soil is a loose surface layer on land that is fertile and capable of growing plants, and it is the material condition basis for plants to survive. Therefore, whether the soil composition is suitable determines the future growth and harvest of the plant. In addition to some uncontrollable weather factors, soil fertility, temperature and water content also play a vital role in the health of crops. Soil water is the source for the survival of land plants, and the amount of soil water content is expressed by soil moisture. Soil temperature has a great influence on the growth and development of crops, the activities of microorganisms, the transformation of various nutrients, and the evaporation of soil moisture. Soil fertility, that is, low or high salt content in the soil is not conducive to the growth of plants. For example, excessive application of phosphate and potassium fertilizers to the soil will easily cause soil compaction. Different plant species have different requirements for soil temperature, water content and salinity. In agricultural planting, in order to get the pulse of soil health, it is necessary to monitor soil moisture. There are many ways to monitor soil moisture, but the most commonly used method is to measure soil moisture. Soil electrical conductivity, soil temperature and moisture three-in-one sensor, which can measure soil moisture, temperature, electrical conductivity and salinity and other parameters. The soil moisture content is calculated according to the volume percentage of moisture, which is in line with the current international Standard soil moisture measurement method; high-density epoxy resin is used for high-temperature vacuum filling between the probe and the body to be completely sealed, and the probe is inserted into the design, which is resistant to acid and alkali corrosion; the body protection level is IP68, and it can be buried in the soil or Put directly into the water for long-term dynamic detection. Currently, the conductivity, soil temperature and moisture three-in-one sensor is widely used in scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, rapid soil testing, plant cultivation, sewage treatment, food Storage and measurement of moisture content and temperature of various particles. What if you want to obtain real-time soil moisture information? We can use a soil moisture monitoring system. The soil moisture monitoring system is composed of soil moisture sensors, weather monitoring host, and cloud platform. The soil moisture sensor monitors the soil water content, electrical conductivity and temperature in real time, uploads the data to the cloud platform through the weather monitoring host, and supports APP and WeChat viewing. The cloud platform has the characteristics of intelligence and automation. After the sensor transmits the data to the cloud platform, users can use the cloud platform to monitor the temperature and moisture content of the soil in real time and understand its chemical composition through the cloud platform. When the soil moisture content or the content of nitrogen, potassium, phosphorus, sulfur and other elements reach non-ideal values, the growers can be notified via text messages, emails, and phone calls, so that they can take timely measures to minimize losses. In addition, the user sets the upper and lower limits of soil moisture, temperature and conductivity through the monitoring host or cloud platform. For example, if the cloud platform receives the soil moisture value below the limit, the cloud platform will automatically Send a linkage command to the host, and the host immediately instructs the M88 industrial control module to turn on the irrigation equipment, and when the soil moisture content approaches the upper limit, the system will automatically turn off the irrigation system. The soil moisture monitoring system keeps the pulse of soil health, making agriculture more scientific, smarter and more convenient. By using the soil moisture monitoring system to monitor soil moisture in real time, it helps us to understand the conditions of various soil parameters in time, and adopt scientific and reasonable irrigation methods based on the growth of plants, which can save water resources; timely and appropriate irrigation not only protects the land It can also increase the area and yield of planting plants, improve the efficiency of irrigation, and promote the high yield of planting plants in the irrigation area. By understanding the content of nitrogen, phosphorus and potassium in the soil, soil fertility can be better improved. The intelligent agricultural system based on sensor technology is the only way for China to develop high-efficiency agriculture and precision agriculture.
