Smart Agriculture Greenhouse
The increase in agricultural greenhouse production is facilitated by CO2 sensors
Compared with traditional agriculture, greenhouse planting is an intensive industry. In the current greenhouse projects, the main economic crops are vegetables, flowers, medicinal materials, etc. For agricultural planting, greenhouses can provide a relatively stable and controllable planting environment to improve the stable yield and quality assurance of crops. At the same time, greenhouse planting can also achieve mechanized control and reduce labor costs.
Carbon dioxide is one of the raw materials for plants to carry out photosynthesis. The level of carbon dioxide concentration directly affects the growth quality of crops:
- Excessive carbon dioxide concentration: it often causes the leaves of vegetable crops to curl, which affects the normal progress of photosynthesis, affects the absorption of oxygen by crops, and cannot carry out normal respiration and metabolism.
- Insufficient carbon dioxide concentration: it often causes dark and dull leaves, late flowering, few female flowers, and many flowers and fruits falling off; the leaf surface is uneven; there are many heteromorphic fruits, low yield, and few high-quality fruits.
- Normal carbon dioxide concentration: It can ensure the health of vegetables, increase the chlorophyll content, make the leaves dark green and shiny; make it bloom early, with less flower and fruit drop, healthy leaf and branch growth, nice fruit and high yield.
Carbon dioxide gas fertilizer
- Carbon dioxide gas fertilizer can be used in the early stage of cultivation, the fertilization effect will be better when the carbon dioxide absorption increases sharply. It depends on factors such as crop species, cultivation methods, growth conditions and environmental conditions.
- The fertilization concentration of carbon dioxide is closely related to the crop species, growth stage, weather conditions and other conditions. Under suitable conditions of temperature, light, water, fertilizer, etc., the photosynthetic rate of general vegetable crops is the fastest when the carbon dioxide concentration is 600-1500ppm. The carbon dioxide concentration of fruits and vegetables is best at 1000-1500ppm, and the carbon dioxide concentration of leafy vegetables is best at 1000ppm.

The lack of carbon dioxide has become one of the important reasons for limiting the output of greenhouse planting. Therefore, many farmers now add a certain amount of gas fertilizer to the greenhouse planting to increase the content of carbon dioxide in order to make the vegetables grow better and increase the yield. Therefore, CO2 sensor technology is widely used in the field of agricultural greenhouse cultivation.
The greenhouse is a relatively sealed place, and there are a big difference in carbon dioxide concentration inside and outside. During the day, the plants in the greenhouse have vigorous photosynthesis, and the carbon dioxide concentration drops sharply; at night, the photosynthesis stops, and the crop respiration releases carbon dioxide, the indoor carbon dioxide concentration gradually increases. The CO2 sensor in the greenhouse can monitor the carbon dioxide concentration in real time, which plays a very important role in the growth of crops.
There are many categories of CO2 sensors, different products are often designed according to different environments. Therefore, users should purchase equipment according to their actual needs. According to the characteristics of agricultural greenhouses, Winsen Technology has developed and produced a series of non-dispersive infrared (NDIR)CO2 sensors suitable for agricultural planting greenhouses.
Smart agricultural greenhouse solutions:
1. With the ability to monitor the environment: indoor temperature and humidity, indoor CO2 concentration, indoor CO concentration, etc.
2. With the ability to control greenhouse equipment: indoor and outdoor sunshade curtains, indoor thermal insulation curtains, humidification system, fill light, water heating control system, CO2 gas supply, alarm, etc.
3. Easy to operate: the management personnel can remotely control the parameters through the PC in the office, and the site staff can adjust the parameters through the keyboard on the controller
