Soil NPK sensor measures soil nutrition

The importance of using soil nitrogen, phosphorus and potassium sensors:

Using NPK soil sensors can easily measure soil nutrient content. Measuring soil content N (nitrogen), P (phosphorus) and K (potassium) is necessary to determine how much additional nutrients will be added to the soil to improve crop fertility.

Use NPK sensors to detect soil fertility. The main components of soil fertilizer are nitrogen, phosphorus and potassium. Knowledge of soil nutrient concentration can help us understand the nutrient deficiency or abundance in the soil used to support plant production.

The working principle of soil sensor:

The soil moisture sensor (or "fdr soil moisture sensor") measures the moisture content in the soil and can be used to estimate the amount of water stored in the profile, or how much irrigation is needed to reach the required saturation. These sensors can be portable, used for instant measurement or installed for long-term monitoring.

There are no commercially available soil moisture sensors that directly measure water. Instead, they measure changes in other soil properties related to water content in a predictable manner. Another soil property becomes the synonym for water content. Common soil properties that vary from water content and are easy to measure include dielectric permittivity and substrate potential.

The sensor that measures the permittivity of the dielectric is the most common type of soil moisture sensor. These sensors use different technologies to measure the permissibility of the surrounding soil.

In order for any soil probe to work, regardless of its type, it must be in contact with the soil. When the soil probe is completely surrounded by soil, maximum accuracy will be obtained, and there are no gaps or pores between the probe and the soil. The detector then sends electrical signals to the soil, measures the response, and passes this information to the data logger (or directly to the cloud via a networked wireless network).
