ABSTRACT:
An omni-directional infrared sensing circuit includes a plurality of infrared sensors positioned in an different-angled space for receiving external remote control signal, a decoder for checking whether the remote control signal is effective, if positive outputting an effective indicating signal, a multiplexer device connected to the sensors for cyclically allowing one of the sensors to transmit remote control signal, a lock device connected to the multiplexer device responding to the effective indicating signal from the decoder and stop the circulation of the multiplexer device.
