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;

Humidity sensors can be generally divided into capacitive, resistive, ion sensitive, light intensity, and surface acoustic wave types according to their measurement principles.

Regarding the common types of soil moisture sensor liquid level sensors, the main methods for measuring soil moisture on the market currently include neutron attenuation method, tensiometer moisture measurement method, and dielectric method speed measurement method.

Soil temperature sensors are distinguished by interface type. Of course, due to the need for sensors in some industries to exchange data with terminal devices in some characteristic forms, several interface methods have appeared before and after.1. RS485 serial port type;2. RS232 serial output;3. Universal network cable interface output;4. USB output mode;

Applications of soil temperature sensor:The soil temperature sensor is widely used in the measurement and research of agriculture, forestry, geology, farmland, water conservancy, forest, lawn, highway, railway maintenance and other aspects.

soil moisture sensor is to monitor the humidity of the soil, and its hardware control circuit is buried in the soil moisture sensor at the root of the crop to monitor the moisture of the root soil. It is transmitted to the main controller, and the main controller determines the control state.

Soil moisture sensor is also known as: soil moisture sensor, soil moisture sensor, soil moisture sensor. Mainly used to measure soil volumetric water content, soil moisture monitoring and agricultural irrigation and forestry protection The commonly used soil moisture sensors are FDR type and TDR type, namely frequency domain type and time domain type.

soil temperature and humidity recorder is composed of two sensors, namely the soil moisture sensor and the soil temperature sensor. It is precisely because multiple sensors can be connected that multiple parameters can be measured simultaneously. The multi-point soil temperature and humidity recorder is the most important instrument in soil testing instruments.

soil moisture monitoring station is developed and supplied by NiuBoL. This solution is suitable for long-term monitoring of soil moisture and soil temperature. Users can flexibly arrange sensors according to the needs of monitoring, and can arrange sensors in different soils.
