Lora/RS485/4-20mA Soil NPK sensor Soil nutrient sensor with high precision for agricultural greenhouse. Soil matric potential is the pressure it takes to extract water from the soil and is a gauge of stress to plants and crops. Profiling probes measure soil moisture across a vertical soil profile, covering a range of one foot to four feet. This allows farmers to turn soil sensor readings, weather, and historical crop data into actionable perception by seeing the bigger picture. As the water content of the soil increases, the dielectric constant of the soil increases, because the dielectric constant of water is much larger than the other soil components, including air. When thinking about an ideal precision agriculture system, producers visualize a sensor located in direct contact with, or close to, the ground and connected to a “black box” which analyzes sensor response, processes the data, and changes the application rate instantaneously. Portable soil sensors provide the user an instantaneous reading of soil moisture in a battery-powered, self-contained unit that can be carried anywhere. Finally, water is essential for photosynthesis. To simply put it, resistive soil moisture sensor work by using the relationship between electrical resistance and water content to gauge the moisture levels of the soil. In agriculture applications, soil moisture monitoring is one of the important factors for improvement in the crop yield and for the plant growth because if the moisture content of the soil is optimum (between the wilting point and field capacity) then plants can gradually absorb the soil moisture and hence an improvement in the plant yields [].
