Apparatus and method for processing sensing data

An apparatus for processing sensing data, comprising:

• an amplifier amplifying analog sensing data inputted from an outside source;
• an analog-digital converter converting the amplified analog sensing data into digital sensing data;
• a micro controller unit (MCU) including a signal modulator modulating the digital sensing data to a data wave having a sound waveform, the data wave transmitted to a sound input port of a terminal;
• and
• an output unit having a sound output terminal corresponding to the sound input port and outputting the data wave to the sound input port through the sound output terminal, wherein the data wave inputted to the sound input port is converted to an information value corresponding to the analog sensing data, and the information value is displayed on the terminal, wherein the data wave includes a sine wave obtained by modulating a binary value of the digital sensing data, the sine wave having a first frequency or a second frequency, wherein the signal modulator modulates the digital sensing data into a plurality of data waves, and the signal modulator generates an overall-bit separation wave having a fourth frequency lower than the first and second frequencies, and wherein the overall-bit separation wave is outputted after a last one of the plurality of data waves is outputted.

• inputting the data wave to the terminal through a sound output terminal corresponding to the sound input port;
• converting the data wave into an information value corresponding to the analog sensing data;
• and
• displaying the information value corresponding to the analog sensing data on the terminal, wherein the data wave includes a sine wave obtained by modulating a binary value of the digital sensing data, the sine wave having a first frequency or a second frequency, wherein the signal modulator generates an inter-bit separation wave having a third frequency lower than the first and second frequencies, and wherein inter-bit separation wave is outputted between the data wave and a second data wave positioned adjacent to the data wave.
