The application of soil moisture monitoring system can measure soil water content and soil temperature at regular and fixed points, and provide data support for the monitoring of seedling, insect and water conditions of crops.

Soil moisture sensor, also known as soil moisture sensor, soil moisture sensor. The soil moisture sensor is composed of stainless steel probes and waterproof probes, which can be buried in soil and dams for a long time to perform fixed-point monitoring and online measurement of soil moisture in surface and deep layers.

The monitoring and forecasting of farmland soil moisture by soil moisture monitoring stations has become an important part of farmland water-saving technology promotion and information services, and plays an important role in comprehensively promoting the application of refined agricultural technology and production management.

NiuBoL soil moisture monitoring system can realize long-term continuous monitoring of soil moisture. Users can flexibly arrange soil moisture sensors according to monitoring needs; they can also arrange sensors at different depths to measure soil moisture in profiles.

How to repair the failure of automatic weather observation station?First of all, it is necessary to determine the fault location, such as power failure, collector failure, sensor failure, communication module failure, etc. Secondly, it is necessary to determine the cause of the failure, whether it is a mechanical failure, a human cause, or an environmental cause.

The role of small meteorological observatories in agriculture, industry and forestry? In different fields, instruments play different roles. The agricultural field is mainly used to understand the weather and soil moisture, while the forest field is mainly used for fire prevention and disaster prevention.

What is the role of the farmland microclimate observation station? This instrument can usually help people understand the changing trends of moisture content, seedling situation and disaster situation in the farmland, and facilitate people to formulate various countermeasures.

working principle of the ultrasonic wind speed sensor is to use the ultrasonic time difference method to measure the wind speed. Because of the speed of sound in the air, it will be superimposed with the speed of the airflow in the wind direction. If the ultrasonic wave travels in the same direction as the wind, its speed will increase;

The velocity of airflow measured by a thermal air speed sensor is a function of current and resistance. By keeping the current (or resistance) constant, the measured airflow speed corresponds only to the resistance (or current).

wind speed sensor is a very common type of wind speed sensor, the sensing part of which consists of three or four conical or hemispherical empty cups. The hollow cups are fixed on trigonal star-shaped brackets at 120° to each other or on cross-shaped brackets at 90° to each other, with the concave surfaces of the cups aligned in one direction and the entire cross-arm frame fixed on a vertical ax···
