background: Soil is our important natural resource. It is the most important basic guarantee in agricultural production. The quality of the soil directly affects the growth of the job. Soil moisture is a very important indicator for studying the energy and material exchange in the soil-plant-atmosphere complex system. It is an important parameter for farmland […]

Background: The purpose of observation of greenhouse microclimate is to understand the meteorological effects of greenhouse measures. The microclimate performance of the greenhouse. The meteorological station is also suitable for parallel observation of crop greenhouse environment. To determine the agro-meteorological indicators of crops or the microclimate effect of greenhouse regulation measures. It can also be

The importance of pH to plants Monitoring soil pH is an important part of maintaining crop health. The optimal soil environment for plant growth is usually between 5.5 and 6.5. Although some plants may thrive in more acidic or alkaline soils. In addition, soil nutrients are closely related to soil pH. In fact, proper pH

Background: In recent years, air quality problems have become a major problem that plagues us. With the development of science and technology in our country. The economic level and the level of urbanization are constantly improving. But our air quality is also declining. The smog seriously endangers our health. The destruction of air quality not

The development background of ultrasonic level gauge: Ultrasonic level gauge are a series of non-contact, high reliability, low price, maintenance-free level gauges. It completely solves the problems of winding, leakage and contact with the medium caused by pressure transmitters. Capacitive floats and other measurement methods. Costly maintenance and other troubles, ultrasonic gauges can meet most

Water quality environmental monitoring is the basis for rational use of water resources and protection of water resources. It is a strategic element directly related to the health of the people and an important measure for the implementation of sustainable development. Global water pollution is getting more and more serious, and water quality environmental monitoring

Background: soil sensors for agriculture enterprises and cooperatives should speed up the harvesting of potato underground tubers and open-field vegetables. Prevent frostbite and frostbite. So as not to cause unnecessary losses. All regions need to strengthen the management of agriculture and animal husbandry production. Guide the windproof and heat preservation of the facility greenhouses and

Background: The soil sensor homekit can be used to measure soil temperature. The factors affecting the growth and development of crops are soil temperature and humidity. Soil temperature, rainfall, light intensity, etc. The change of soil temperature affects the activities of various microorganisms. Understanding soil temperature plays an important role in improving crop output efficiency

Overview: The wind direction sensor is an instrument used to measure wind direction. Detect and perceive external wind direction information through the rotation of the wind direction arrow. And transmit it to the coaxial code disc, and output the corresponding wind direction value at the same time. The wind direction sensor can measure the near-ground

Introduction of COD: Chemical oxygen demand. COD is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. Oxygen equivalent of substances that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. In the study of river pollution and the
