As a new industry, facility agricultural production has fully demonstrated its inestimable economic and social benefits, and has become an important part of modern agriculture. In recent years, the area of ​​solar greenhouses in China has been growing rapidly. It has become the main type of winter vegetable planting in the Three North Region, especially in North China. However, the changes in the internal environment of the greenhouse are mainly affected by changes in the outside world, especially low-temperature diurnal illumination, strong cooling, strong winds, heavy snow, and other severe weather. Therefore, the meteorological conditions of facility agriculture are monitored and severe weather forecasts are issued to early warning of greenhouses. Efficient production is very important. The small-scale automatic weather station was developed to meet the needs of facility agriculture.
Specialized meteorological services for facility agriculture are still being explored, and few have actually become operational. The premise of conducting forecasting and warning service is to observe the microclimate within the solar greenhouse for a long time. At present, there are several small-scale automatic meteorological stations in the field for meteorological systems throughout the country. However, in the high-temperature and high-humidity environment of the greenhouse, the hand-held meteorological station is difficult to guarantee the stability and reliability of the work. Therefore, there is a need to develop meteorological observation equipment that serves the microclimatic observations of facility agriculture. The field microclimate automatic observer is an agricultural meteorological observation device developed by Top Instruments, which can observe the temperature, humidity, carbon dioxide concentration, total radiation, photosynthetically active radiation and other factors in agricultural greenhouses. The observations can be transmitted wirelessly. Can be stored in the SD card, call out the data through the reader. The randomly equipped power supply system can provide more than 7d of working power in locations where there is no mains, and is equipped with solar panels to ensure the reliability of the data. The entire system can also be equipped with an LED large-screen display system that can display the measurement results in real time.
