The purpose of the hazardous odour source monitoring method in WSN mode is to effectively monitor environmentally hazardous odour sources and provide early warning of pollution sources. The experimental results show that the WSN-based environmental hazard odour monitoring method can effectively monitor the hazardous odours in real time, and provide decision support basis for toxic and harmful leakage source monitoring, pollution control and pollution source tracking, and early detection and early warning of fire sources.
