摘要：A battery-saving apparatus of an active RF remote controller using a moving detector and a method for controlling the same are provided to suppress unnecessary power consumption by making the active RF remote controller turned on only when a user walks, thereby extending the life span of a battery. If a detection signal based on a user's walking state is inputted to a control part from a moving detector(100), a power supply part gets switched on according to control of the control part so that power can be supplied to an active RF remote controller(200). An RF signal transmitting part outputs RF signals of a specific frequency band under control of the control part(300). At this time, the control part judges whether RF signals were outputted repeatedly over 10 times(310). If it is judged that RF signals were outputted repeatedly over 10 times, the control part judges whether detection signals are continuously inputted through the moving detector as the user walks(400). In case no more detection signals are inputted from the moving detector, the control part turns off the power supply part to cut off power supply to the active RF remote controller(500).
