The agricultural meteorological station can monitor conventional meteorological factors (atmospheric temperature, environmental humidity, average wind speed and direction, instantaneous wind speed and direction, precipitation, hours of sunshine, direct solar radiation, dew point temperature, soil temperature, soil heat flux, soil moisture, leaf surface Humidity) for direct measurement, can also measure water surface evaporation, solar photosynthetic active radiation and other factors. Based on the monitoring of environmental parameters, it realizes automatic monitoring of integrated ecological information of facility agriculture, automatic control and intelligent management of the environment.
Composition of agricultural weather station：
(1) Temperature and humidity monitoring
The temperature and humidity sensor monitors ambient air temperature and humidity, surface temperature and humidity, soil temperature and humidity, etc., and can collect, analyze, calculate, control, store, and send data.
(2) Illumination monitoring
The intensity of the recorded light is monitored by the light sensor and photosensitive sensor, and the relevant data is transmitted to the user monitoring terminal through the wireless transmission technology.
(3) CO2 and O2 concentration monitoring
Deploy a carbon dioxide concentration sensor at the monitoring site to monitor the content of carbon dioxide in real time. When the concentration exceeds the threshold range set by the system, the relevant data will be transmitted to the user monitoring terminal through wireless transmission technology, and the relevant staff will make corresponding adjustments.
(4) Wind speed and wind direction monitoring
The wind speed sensor and wind direction sensor are used to automatically measure the real-time wind speed and wind direction, and the wind speed and wind direction level can be displayed in real time on the display screen. At the same time, it has an audio alarm function.
(5) Rainfall monitoring
The rain gauge can be used to detect, store, display, and alarm the amount of rain. Rainfall data can be tracked and recorded throughout the entire process, with long recording time, large storage capacity, and convenient data viewing. The recorded data can be exported to a computer at any time, and can be stored as an EXCEL table file to generate a data curve for further analysis by other analysis software. deal with.
(6) Solar radiation monitoring
Convert the received solar radiant energy into other forms of energy with minimal loss, such as heat and electrical energy, for measurement. Monitoring the revenue and expenditure data of solar radiation is not only helpful for agricultural meteorology and ecology research, but also has important reference value for evaporation, plant transpiration, and water cycle research.
(7) Monitoring of water surface evaporation
Therefore, it is necessary to monitor the evaporation of the water surface. Water surface evaporation monitoring is the use of evaporation sensors to observe the changing laws of water surface evaporation in different time periods, and to grasp the water surface evaporation data in the agricultural environment in real time.
The agricultural weather station supports customization according to user needs and can be used with air quality sensors. The agricultural weather station can be used with the smart agricultural big data cloud platform to monitor air temperature and humidity, wind speed and direction, solar radiation, water volume, water surface evaporation and other data online in real time , The data is clearly displayed, and the mobile phone APP can be used to remotely view the environmental monitoring parameters, and real-time warning is beneficial to the development of smart agriculture.
