PURPOSE: A device for controlling an application apparatus using wireless technology and a sensor for sensing human body is provided to deliver an authentication code to a sensor key from a controller, and to transmit an answering code to the controller from the sensor key only when a code corresponds to the authentication code, thereby reducing changes of wrong operations. CONSTITUTION: A sensor key comprises as follows. An authentication code storage stores an authentication code. A PIC includes a CPU for comparing the authentication code with an authentication code transmitted from a controller and for outputting an answering code only when the two codes are the same. A wireless transceiver delivers the answering code. The controller comprises as follows. A PIR sensor outputs a sensing signal by sensing human body. A microprocessor(27) outputs the authentication code when the sensing signal is inputted. A wireless transceiver(25) delivers the authentication code. An application apparatus controller(29) indicates the microprocessor(27) to control an application apparatus according to the answering code in response to the delivered authentication code.
