As a kind of renewable clean energy, biogas is widely used in rural areas, but its security has become an important issue of the promotion. In recent years, the monitoring of the operation and management of biogas project has become an important problem in the industry. The Internet of Things is a new kind of information technology, which can be based on the sensing technology, the sensor network real-time access to all kinds of data, and can play an important role in the operation of biogas project monitoring. However, in recent years, from the research and practice, we can find that the actual operation of the biogas project monitoring system is still in the primary stage of research. In this paper, based on the actual needs of the operation and management of the Agricultural Bureau of Beijing Agricultural Bureau, the intelligent monitoring system for the operation and management of biogas project is designed and realized. The practical results show that the system has good application effect.
