Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouse gas monitoring, and in particular relates to a greenhouse gas monitoring and alarm device. Background Art

[0002] Greenhouse gases refer to some gases in the atmosphere that can absorb long-wave radiation reflected by the ground and re-emit radiation, such as water vapor, carbon dioxide, most refrigerants, etc. Their function is to make the earth's surface warmer, similar to the role of a greenhouse in intercepting solar radiation and heating the air inside the greenhouse. This effect of greenhouse gases making the earth warmer is called the "greenhouse effect." Water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), freon, methane (CH4), etc. are the main greenhouse gases in the earth's atmosphere.

[0003] Accurate monitoring of greenhouse gases is crucial in fields such as meteorology or greenhouse farming. In order to monitor the concentration of multiple greenhouse gases online, it is necessary to use multiple greenhouse gas concentration online monitoring devices to detect the gas concentration. If the concentration exceeds the range, an alarm notification will be issued. In existing monitoring technologies, the content of various gases in greenhouse gases is mainly obtained through electrochemical sensors. Because greenhouse gases contain water vapor, when performing online monitoring of multiple greenhouse gas concentrations, the electrochemical sensors themselves are affected by humidity for a long time, which will cause the monitoring accuracy to decrease and require regular maintenance. However, due to the large range of humidity changes in greenhouse farming, it is difficult to determine whether the sensor monitoring accuracy falls within the error range, and it is also difficult to determine the time for regular maintenance.
