Abstract: An infrared receiving apparatus and a method thereof are provided to filter the disturbing light of a bandwidth by using an HPF having a pole frequency higher than the bandwidth, and remove signal distortion caused by excessive settling through a reset process by using the waveform characteristic of a received signal, thereby improving a noise characteristic by the disturbing light having a frequency in the bandwidth. A light receiving unit(200) receives infrared signals and provides a voltage signal. An HPF(High Pass Filter) unit(210) filters the signals provided through the light receiving unit in a pole frequency higher than an infrared signal bandwidth. An amplification unit(220) amplifies the output of the HPF unit. A waveform shaping unit(230) shapes the output of the amplification unit on the basis of a reference threshold voltage to provide a square wave. A reset unit determines the output of the amplification unit on the basis of the reference threshold voltage to reset the output of the HPF unit.

Abstract: PURPOSE: A human body sensor system and sensing method of sensor system is provided to realize a low cost sensor system by employing a micro controller(micro processor) for temperature compensation. CONSTITUTION: A human body sensor system(100) comprises an infrared sensor(114) for receiving an infrared signal from a signal source, converting the infrared signal into an electrical signal, and outputting the electrical signal; an amplifier(116) for receiving the electrical signal, amplifying the voltage and outputting the result; a filter(118) for removing noise of high frequency band from the amplified electrical signal; a temperature measuring circuit(130) for outputting an analog signal responsive to the ambient temperature of the infrared sensor; an analog-digital converter(122) for receiving analog signal from the filter and the temperature measuring circuit, converting the analog signal into a digital signal, and outputting the digital signal; and a processor(124) for receiving digital signal, sampling the data, storing the sampled data, calculating sampling variables with respect to the digital signal during a predetermined time period, and comparing the pre-stored characteristics of the signal radiated from a human body with the sampling variables, so as to thereby determine the type of signal source. The processor compensates to prevent erroneous operation of the system caused due to the environmental condition of the infrared sensor, and controls to output an alarm signal in the case the signal source is human.
