Greenhouse environment monitoring

Greenhouses for plant growth condition optimization of closed environment.The optimal control need information from indoor and outdoor environment.Usually, people will be in a greenhouse with carbon dioxide (CO₂),Relative humidityAnd the temperature measurement;Measuring parameters include outdoor wind speed and direction, rainfall, and solar radiation.

Plant requires carbon dioxide to grow - carbohydrates by CO₂And water generated.Plants need to use in photosynthesisCarbon dioxide.Proper CO₂Fertilizer can improve the yield of greenhouses, carbon dioxide fertilization can be during the day or artificial lighting by bottled CO₂Or burner CO₂To complete.The best CO₂Condition depends on plants in greenhouses and lighting conditions.When the light intensity in the greenhouses are decreased, photosynthesis slowing, CO₂Down consumption.Use too much CO₂Would increase the cost of unnecessary and harmful to the crops.

Ventilation plays an important role in agricultural applications indoors,According to the need to control the ventilation (DCV)Can produce remarkable energy saving benefits, because it ensures that the ventilation system in only set a good time every day.Use of DCV can not only save energy, but also can prevent excessive ventilation.Using as little energy as possible to realize fully, the best ventilation.

The same mechanism applies to greenhouses.During the day, when exposed to more light, plant photosynthesis is active, can use DCV optimization CO₂Levels to promote the growth of plants to the greatest extent.At night, plant dormancy, not for photosynthesis.If you know that the ideal growing conditions of a specific plant, can maintain accordingly for ventilation and CO₂Levels of optimization.By contrast, do not measure CO₂, pure control system based on time will only simple based on the same amount of time to feed CO₂And whether plants can take advantage of it.

Visa can provide used to measure in greenhouseCO₂, relative humidity and temperatureThe instrument.Visa series products include outdoor transducer used to measure wind, precipitation, temperature and humidity parameters of the products.Outdoor transmitter wide working temperature range, is suitable for the vast majority of climate conditions, installation flexibility, and equipped with protection equipment of sun shade and radiation protection cover.
