soil moisture sensor is a sensor that measures soil moisture. By measuring the dielectric constant of the soil, it can directly and stably reflect the true moisture content of various soils.The soil temperature and humidity recorder is composed of two sensors, the soil moisture sensor and the soil temperature sensor.

Soil moisture monitoring station monitoring and forecasting of soil moisture in farmland has become an important part of the promotion of farmland water conservation technology and information services, and plays an important role in promoting the application of modern agricultural science and technology and production management level.

Temperature, humidity, conductivity three-in-one soil sensor is a set of soil temperature, soil moisture, soil conductivity three in one multifunctional soil sensor, product parameters can be optional according to the actual situation, can achieve real-time monitoring of soil environmental parameters.

Soil moisture sensor is also known as: soil moisture sensor, soil moisture sensor, soil water content sensor. It is mainly used to measure soil volume water content, do soil moisture monitoring and agricultural irrigation and forestry protection.

Most landslide phenomena are caused by heavy rainfall, and the infiltration of rainfall is the main cause of landslides. Based on this, the landslide monitoring equipment tries to monitor the change of soil moisture of the mountain in real time by adding a soil moisture sensor.

Soil moisture monitoring station is a professional equipment used to monitor soil moisture in the field, it can use its data collection, transmission and storage technology to obtain real-time field moisture and drought information, and the staff can analyze the current soil moisture situation in the field through these data information.

soil moisture monitoring system can be extended with multiple sensors to monitor more environmental information, such as soil water potential, UV radiation, light intensity, atmospheric humidity, wind speed and direction, etc. The instrument is charged by solar panel and can work normally regardless of cloudy or sunny days, which is very suitable to be placed in the field for long-term monitoring ···

soil moisture sensors commonly used nowadays are FDR type and TDR type, i.e. frequency domain type and time domain type. At present, the more popular is FDR type, FDR frequency domain reflectometer is a kind of instrument used to measure soil moisture, it has the advantages of easy and safe, fast and accurate, fixed point continuous, automation, wide range, less calibration, etc..

Soil Moisture Sensor Wide application: small impact of soil texture, wide application area, to achieve low-cost application program.

Through the research on three kinds of soil moisture sensors, it can be seen that the capacitive soil moisture sensor is composed of interdigitated aluminum strips to form the electrodes of the capacitor, and uses air as the dielectric of the capacitor. The capacitance value will also change, so the capacitor can be used as a soil moisture sensor;
