The present invention provides an integrated sensor device and an environment event identification method based on the integrated sensor device. The device comprises a circuit board, at least two physical sensors integrated on the circuit board, a chip integrated on the circuit board, and a communication unit integrated on the circuit board. The physical sensors are used for obtaining original data of an environment. The chip is used for analyzing the original data and identifying environmental events. The communication unit is used for performing data transmission. In the present invention, a high-performance Internet-of-things processor serves as a core, multiple types of sensing elements are integrated on one circuit board, data from the sensors is comprehensively analyzed by means of machine learning algorithms, and accordingly, many-to-many (N:N) universal event detection is implemented, and all sensible events in the environment can be theoretically detected. In the present invention, a concept of integrated sensing is adopted, and various meaningful events occurring in the surrounding environment are sensed from higher dimensions on the premise that privacies of users are fully protected, and universal environmental events are accurately detected.
