The role of carbon dioxide sensors

Carbon dioxide sensors are machines used to detect the concentration of carbon dioxide. Carbon dioxide is one of the raw materials for photosynthesis in green plants, and 95% of the dry weight of a crop comes from photosynthesis. Therefore, the use of carbon dioxide sensors to control the concentration also becomes an important factor in crop yield.

The role of carbon dioxide sensors in greenhouses：

Greenhouse is used to cultivate plants in the facility. It can provide greenhouse fertility and increase yield in the season when it is not suitable for plant growth, and is mostly used for cultivation or seedling of temperature-loving vegetables, flowers, forest trees and other plants in the low temperature season. It is a relatively closed environment and crops are constantly photosynthesizing inside the greenhouse, therefore, the carbon dioxide concentration in the greenhouse is significantly different from the outside environment.

The carbon dioxide content in the greenhouse directly affects the growth of crops, too much or too little carbon dioxide will have certain effects on the crops. When the carbon dioxide is sufficient, it can ensure the healthy growth of vegetables, make the chlorophyll content rise, the leaves are dark green and shiny; make them bloom early, less flowers and fruits fall, the leaves and branches grow healthy, the fruits are correct, early market, and the yield is high.

Effects of insufficient or excessive CO2 levels in greenhouses on plant growth:

Insufficient CO2 content: CO2 is the "food" for plants, and low CO2 concentration makes plants "starve", which has a great impact on plant biomass. For example, vegetables lacking CO2 have dark and lustrous leaves, poor plant growth, late flowering, few female flowers, more flowers and fruits falling off, low flat leaves, vertical or pendulous with the main branches, uneven leaf surface, more heterogeneous fruits, 2-3 days late to market, low yield and few high quality fruits.

Excessive carbon dioxide content: carbon dioxide concentration is too high, often causing vegetable crops leaf curl, affecting the normal conduct of photosynthesis, will affect the crop's absorption of oxygen, can not carry out the normal respiratory metabolic action. 

So many growers in order to make vegetables grow better to improve production, will add a certain amount of gas fertilizer in the greenhouse planting (currently developed gas fertilizer is mainly carbon dioxide, because carbon dioxide is an essential raw material for plants to carry out photosynthesis. Within a certain range. The higher the concentration of carbon dioxide, the stronger the photosynthesis of plants, so carbon dioxide is a good gas fertilizer.) The higher the concentration of carbon dioxide, the higher the level of carbon dioxide.

Installing carbon dioxide sensors in the greenhouse can ensure the timely alarm in case of insufficient carbon dioxide concentration, so that gas fertilizer can be used. It ensures early release, high quality and high yield of vegetables, edible mushrooms, flowers and herbs. Carbon dioxide sensors determine the growth and development of crops, maturity, resistance, quality, yield, etc.

The working principle of carbon dioxide detector

图片
The working principle of carbon dioxide detector The working principle of the CO2 detector is mainly based on the infrared light source absorption principle. The following is the detailed working mechanism: Infrared absorption principle: Carbon dioxide detectors detect carbon dioxide gas in the environment through the absorption properties of infrared light sources. Specifically, carbon dioxide molecules have absorption properties for infrared light of specific wavelengths, especially infrared light with a wavelength of approximately 4.26 microns (4260 nanometre ). Measuring chamber and light source: The gas to be measured is introduced into a measuring chamber with an infrared light source mounted at one end of the chamber and a filter and detector at the other end. The filter allows infrared light of a specific wavelength to pass through, while the detector measures the luminous flux through the chamber. Detector Measurement: The amount of light flux received by the detector depends...

Introduction of temperature and humidity data recorder A temperature and humidity data logger is a device used to monitor and record changes in temperature and humidity in the environment. It has an important role in many areas, such as: In the laboratory, it can ensure that the experiment is carried out under the appropriate temperature and humidity conditions to ensure the accuracy of the experimental results. In the storage place, it helps the management to monitor the temperature and humidity inside the warehouse to prevent the goods from getting damp or mildew. In the production workshop, the temperature and humidity of the production environment can be monitored to ensure the normal progress of the production process. Type of temperature and humidity data logger Digital temperature and humidity recorder Features: The temperature and humidity data in the environment is collected by the sensor and displayed in digital form. This type is more common, simple and intuitive operation,...

Weather Forecasting

图片
  The Importance of Weather Forecasting Weather forecasting has an extremely important impact on our daily lives, economic activities and social security. The following are some of the main aspects: 1. Prevention of natural disasters Weather forecasts can predict possible weather disasters in advance, such as heavy rain, typhoons, snowstorms, etc., so as to take appropriate precautions to reduce the loss of life and property.   2. Planning life and production activities People can understand the future weather changes through the forecast, reasonable planning of travel, tourism, outdoor activities, etc., to improve the convenience and safety of life. For agricultural production, weather forecasts can provide farmers with references for agricultural activities such as sowing, fertile  application, irrigation, etc., so as to improve the efficiency of agricultural production and yield.   3. Emergency response When emergencies occur, such as epidemics, earthquakes, etc.,...
