PM2.5 is a fine particulate matter in the air that is harmful to human health, and its concentration directly reflects the quality of air. PM2.5 sensor is a device that can accurately measure the concentration of PM2.5 in the air in real time, and its working principle is mainly based on the light scattering method. With PM2.5 sensor, we can understand and monitor the air quality in time, so that ···

Both 2D and 3D anemometers are important wind speed measurement tools, and they have their own advantages and applications in monitoring wind speed and direction. 2D anemometers are suitable for situations where the need for vertical wind speed measurement is not high, while 3D anemometers are suitable for complex environments where comprehensive information about the wind field is required. Users···

ultrasonic sensors in the application need to pay attention to its susceptibility to environmental influences, sensitive to surface roughness, the existence of ranging blind zones, diffusion angle and directional limitations, triangulation errors, susceptibility to noise and measurement speed limitations and other disadvantages. In practical applications, it is necessary to choose the appropriate ···

IoT agriculture and agricultural IoT are one of the important directions for the development of modern agriculture, and they realise the intelligent, efficient and sustainable development of the agricultural production process through high-tech means. The future of agricultural IoT is full of opportunities and challenges, and it is expected to lead agriculture into a new era of more efficient, int···

Soil pH not only affects the chemical and biological properties of the soil, but is also directly related to the efficiency and sustainability of agricultural production. By regularly testing and adjusting soil pH, soil conditions can be optimised for healthy crop growth. Soil pH sensor is widely used in agriculture, environmental monitoring and scientific research. It can help farmers and horticu···

TDR and FDR are both excellent soil moisture sensor technologies, and the choice of sensor depends on specific needs, budget and installation conditions. The choice should be based on the user's needs, budget and the actual application scenario. If you require high measurement accuracy, you can choose the TDR sensor; if you have a limited budget and certain requirements for sensor stability, the F···

Tipping bucket rain gauge is an indispensable rainfall measurement tool in meteorological, hydrological, agricultural and other fields, and its price varies depending on the material and type.ABS rain gauge is affordable, about 60-100 USD, suitable for users with limited budget; stainless steel durable type costs 100-200 USD; and high-precision double tipping bucket design is more expensive, about···

The application of automatic weather station in modern agriculture is of great value. It not only provides accurate meteorological data and prediction information for agricultural production, helps farmers to carry out scientific management and improve the efficiency of agricultural production, but also plays a key role in disaster early warning and prevention, which guarantees the stability and s···

The construction of weather stations requires approval from the Meteorological Bureau, land, environmental protection and urban planning departments, as well as attention to safety issues such as equipment, lightning, electricity and the environment. Construction details include site selection, infrastructure construction, ventilation conditions, representativeness, equipment selection, data trans···

The operation of weather stations needs to pay attention to the risks of natural disasters, technological updating, market competition, policies and regulations and human resources, and to reduce operational risks through measures such as strengthening early warning, technological innovation, market adaptation, policy tracking and personnel training. At the same time, attention has been paid to da···
