The invention discloses a low-power-consumption wake-up method based on a specific feature code, which comprises the following steps of: 1, connecting a signal receiving module to an external interrupt pin of a control module, configuring the pin to be in a rising edge interrupt trigger mode or a falling edge interrupt trigger mode, taking the pin as a trigger pin for wake-up judgment and taking the pin as a falling edge interrupt trigger mode, wherein the pins are receiving pins for receiving feature code signals, and the equipment works in a low-power-consumption state; 2, after the external interrupt pin is triggered, switching to an interrupt service function, and starting to record information received by the external interrupt pin; and 3, after recording is completed, judging whether information received by the external interrupt pin is matched with a preset feature code or not, if yes, awakening the device, and if not, executing the step 2, and waiting the next interrupt to be triggered.
