Abstract: An apparatus and method for controlling a sensor node are provided that may calculate an azimuth angle and a slope of the sensor node using a 2-axis magnetic sensor and a 3-axis acceleration sensor, and may detect a target approaching the sensor node. The apparatus may include a calculation unit to calculate an azimuth angle and a slope of a sensor node, based on a magnetic values measured by a 2-axis magnetic sensor and a acceleration values measured by a 3-axis acceleration sensor; a sensor control unit to filter the magnetic values and the vibration values and to amplify the filtered magnetic values and the filtered vibration values, when the azimuth angle and the slope are calculated; and a detection unit to detect a target based on the amplified magnetic values and the amplified vibration values.
