[0002] Greenhouse gases refer to a class of gases that exist in the earth's atmosphere and play an important role in the greenhouse effect. They mainly include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6). These gases can absorb and re-radiate long-wave radiation emitted from the earth's surface, causing the earth's temperature to rise, thus forming a greenhouse effect.

[0003] In order to cope with climate change and reduce greenhouse gas emissions, it is necessary to monitor the greenhouse gases produced. Existing greenhouse gas monitoring technologies are mostly based on manual monitoring. If the changes in greenhouse gases are to be monitored for a long time, the workload is relatively large, the monitoring efficiency is not high, and abnormalities cannot be discovered in time during the monitoring process. At the same time, the current monitoring equipment is relatively complex and bulky, and it is not easy to move when monitoring outdoors. Therefore, in order to solve the above problems, the present invention combines multi-source sensing technology and Internet of Things technology to provide a small and portable greenhouse gas remote monitoring device.
