1. A remote-control system, comprising:
a remote controller including a motion sensing circuit and a first wireless communication circuit electrically connected to the motion sensing circuit, wherein the motion sensing circuit determines whether or not a motion of the remote controller complies with one of a plurality of reference motions; and
a second wireless communication circuit configured to be disposed in a controlled device;
wherein, when the motion of the remote controller complies with one of the plurality of reference motions, the first wireless communication circuit is switched from a sleep state to a working state;
wherein the first wireless communication circuit or the second wireless communication circuit determines whether or not a received signal strength indication (RSSI) between the remote controller and the controlled device is greater than or equal to a strength threshold;
wherein, when the received signal strength indication is smaller than the strength threshold, the remote controller is switched from the working state to the sleep state.
