The invention discloses a sensor automatic recognition method and device of a water quality monitoring terminal, and relates to the field of water quality monitoring. The method comprises the following steps: powering up all sensor channels, and reading the type ID and the communication address of the sensor of each channel in the archive of the sensor; searching a parameter register address corresponding to the type ID of the sensor in a preset parameter library according to the type ID of the sensor; protocol framing is automatically completed according to the communication address of the sensor and the register address; information of the sensor is read through the bus interface monitoring terminal. The monitoring terminal can automatically identify a plurality of different types or a plurality of sensors of the same type accessed to the water quality sensor by adopting a bus interface, and a sensor communication address does not need to be independently set and matched with a default address of the monito
