The invention relates to a dangerous atmosphere comprehensive state fingerprint identification method, which mainly solves the problems that the current sensor monitoring systems have no multipath detection capability, complex atmosphere state identification and real-time early warning cannot be realized, wireless signal transmission is lacked, cloud signal storage is lacked, large data analysis is lacked, and self-learning is lacked in the prior art. According to the fingerprint identification method, the dangerous atmosphere comprehensive state fingerprint identification is carried out by a dangerous atmosphere comprehensive state fingerprint identification system for users, the dangerous atmosphere comprehensive state fingerprint identification system comprises a sensing chip, a signal conditioning module, a signal transmission module, an air passage control module, a temperature control module and a data processing module, which can better solve the above problems, and the system can be used for dangerous atmosphere comprehensive state fingerprint identification.
