The invention provides a method and a device for reducing the dormant power consumption of a sensor node. The device comprises a sensor node and further comprises an external clock module connected with the sensor node, wherein, the sensor node sends a control signal to the external clock module before entering into a dormant state; after receiving the control signal of the sensor node, the external clock module starts to time, and sends an interrupt signal to the sensor node after the time is fixed; and the sensor node receives the interrupt signal of the external clock module and then enters into a working state. The invention is achieved through adding the external clock module on the prior sensor network node; and the change to the prior system is less. In addition, the cost of the external clock module is low; and the influence on the cost of the prior sensor node is not large. Furthermore, after the external clock module is added, the dormancy power consumption of the sensor node can be reduced obviously.
