I. Overview
The intelligent monitoring system for hazardous sources (septic tanks) utilizes the Internet of Things, sensors, edge computing technology, intelligent control technology, data storage technology and big data analysis and processing technology to realize the monitoring points of urban septic tanks, pipe networks, and pipelines as temperature, Real-time data collection, processing, storage, comparison and analysis of liquid level, toxic and harmful gas concentration, etc., and upload the monitoring data to the cloud platform wirelessly. The on-site terminal starts the complete set of gas intelligent disposal equipment, the cloud service platform generates alarm information, and the mobile APP terminal generates alarm information and prompts the user with a prompt tone).

2. Features
