The use of NTC temperature sensor in soil temperature monitoring

　　Agriculture is the basic industry that supports the construction and development of the national economy, and it is also the primary industry in my country. With the development of society, modern agricultural equipment uses machinery and intelligent systems to grow products to improve the efficiency and quality of agricultural production. At the same time, plants need to have differences in growth temperature. In smart agricultural facilities, a built-in NTC temperature sensor is required to monitor the temperature, so as to provide a suitable growth environment for plants.

　　Soil temperature is the temperature in the soil below the ground. It refers to the temperature in the shallow layer below the ground that is directly related to the growth and development of plants. Soil temperature directly affects the degree of plant growth and the rate of fruit ripening. The right temperature is conducive to the growth of the root system of the plant. If the temperature is too high, the root system will be damaged. When the temperature is low, the root system will grow slowly. If the temperature is too low, the root system may be damaged by freezing. But soil temperature changes much more slowly than air temperature. The quality of soil temperature directly affects the growth of plants. Scientific irrigation decision-making enables crops to live in a soil environment where crops are truly comfortable, which is of great benefit to improving crop yields. Therefore, an NTC temperature sensor is required to monitor the temperature.
