CO2 Sensor Applications
01 Greenhouse monitoring
The concentration of carbon dioxide required for vegetables is generally 1000~1500ppm. Therefore, the carbon dioxide deficit in the plastic greenhouse has become an important factor affecting the output of vegetables in the plastic greenhouse. The installation of carbon dioxide gas sensors in the plastic greenhouse can ensure timely alarm in the case of insufficient carbon dioxide concentration, to use gas fertilizer ensure high quality and high yield of vegetables, edible fungi, and flowers.
02 Farming monitoring
Some large farms, such as cattle, pig, chicken factories, etc., are in enclosed or semi-enclosed environments. A large number of livestock will exhale a large amount of carbon dioxide. If ventilation measures are not taken in time, high concentrations of carbon dioxide will cause animal hypoxia, depression, fatigue, anorexia, slow growth, and other problems. At the same time, the lack of air movement can easily lead to a decline in the immunity of livestock and outbreaks of diseases.
03 Industrial waste gas monitoring
As the economy develops and the level of industrialization increases, human activities (such as burning fossil fuels and deforestation) have exacerbated the increase in greenhouse gas concentrations. There are also some industrial enterprises that use chimneys or exhaust gas in the combustion and production process, and a large amount of CO2 gas is discharged from the opening of the pipe. These make global warming one of the biggest challenges facing mankind today.
04 Indoor gas detection
The use of carbon dioxide gas sensors can be seen everywhere in our daily life environment, such as kindergartens, schools, office buildings, shopping malls, supermarkets, gas stations, hospitals, and other public places. Monitoring the concentration of carbon dioxide through a carbon dioxide sensor can improve air quality, thereby improving learning and work efficiency.
FAQs - More information about co2 sensor
Carbon dioxide is a kind of carbon-oxygen compound with the chemical formula of CO2. It is a colorless and odorless gas under normal temperature and pressure. It is also a common greenhouse gas and a component of air (0.03%-0.04% of the total volume of the atmosphere).
Our carbon dioxide sensor has been calibrated before leaving the factory, and there is no need for customers to perform secondary calibration.
co2 sensor working principle: The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules.
First, choose the best co2 sensor according to the place of use: If the measurement environment is not fixed and the measurement time is short, you can choose a portable co2 detector, which can be carried around and is convenient to use. If the detection environment is fixed and need long-term monitoring, wall-mounted carbon dioxide sensor or home carbon dioxide sensor can be selected, which can be monitored after installation. If you want to monitor the CO2 concentration in a flammable and explosive environment, you can choose an explosion-proof co2 sensor. To measure the concentration of co2 in the pipeline, select a duct mount carbon dioxide sensor.
