Provided are a separable device for controlling a node and a sensor network node. The separable node-control device includes: a second interface connecting a power line and a data signal line with the outside; and a power supply for supplying power to the second interface and a sensor unit, wherein the power supply and the second interface are controlled by an external control device combined with the second interface and the controller are driven by power supplied from the external device. According to the separable node-control device and the sensor network node, the node-control device is separated from the sensor network node so that the function of the sensor network node can be readily changed according to need.
