一, product introduction
For temperature, humidity, ground temperature within greenhouse meteorological elements such as 24-hour monitoring records, easy to master the greenhouses
Microclimate inside information, timely and accurate meteorological information, guiding farmers scientific ventilation watering, fertilizing, disaster prevention and mitigation.
Canopy layer of automatic meteorological station monitoring greenhouse in main crops in the formation of the special climate.Growth, development and yield of crops and plant diseases and insect pests have very big effect.Because all sorts of crop community structure is different, between strains of light energy distribution, the characteristics of air temperature and humidity, soil temperature and humidity with bare have significant difference on the ground.Different crops and different plant density, planting distance, row spacing and row, and leaf area size at different stages and so on all can form specific microclimate.Humans can through the technical measures of agriculture to a certain extent, change the greenhouse microclimate.In the intercropping and interplanting tillage work at temperature keep moisture, irrigation, plastic mulching, the agent has made obvious effect.Shed the fundamental goal of automatic meteorological station, the study is to improve greenhouse microclimate condition, in order to improve crop yields.

Greenhouse automatic meteorological station has many functions such as meteorological early warning surveillance and disease, the prevention and control of plant diseases and insect pests, crop production, and business and research analysis provide strong information support, can on the ground of the ecological environment and various meteorological elements (temperature, humidity, wind speed, wind direction, air pressure, precipitation, solar radiation, illumination, soil temperature, soil moisture, etc.) for timing automatic data collection, calculation, processing, display, storage, communications and printing, improve the efficiency of the observation, reduce the labor intensity of the observers.Support for multiple network communication function, through the RS485 interface connected to the computer cable data communication.The system has stable performance, high precision, no duty, strong anti-jamming capability, feature-rich software and so on characteristics.
