1. An infrared sensor, comprising:

  • an infrared generator for generating infrared radiation within a detecting area;

    a pyroelectric sensor electrically communicated with said infrared generator, wherein said infrared radiation as an input signal is converted into a DC signal as an output signal through said pyroelectric sensor, wherein said DC output signal has a real signal with low frequency and a noise signal mixed therewith;

    a microprocessor which comprises a A/D converter electrically connected with said pyroelectric sensor, wherein said microprocessor is arranged to receive said DC signal for data processing so as to determine whether a target locating within said detecting area; and

    an integrated detecting processor, which is electrically connected with said microprocessor, adapted for stripping out said DC signal from said pyroelectric sensor to control a DC level of said DC signal, such that said real signal is allowed to be accurately processed in said microprocessor without data overflowing.
