Low Power PlR Sensing Controller Passive Infrared (PIR) detecting control IC PIR Detecting Control IC HR008 SOP-8pin
General Description
HR008 is a low power PIR(passive infrared) controller, it can be combined with a pyroelectric infiared sensor and a small number of external components to form a PIR switch.
HR008 has a built-in high gain, high input impedance operational amplifier and a fixed gain amplifier, which can be matched with a variety of sensors for signal pre-processing.
HR008 also integrates a built-in LDO with high PSRR, which powers the PlR effectively sensor. improving noise immunity.
HR008 can be set by adjusting peripheral circuit: the detection sensitivity the Output Delay Time, the photosensitive control. etc.
HR008 is assembled in a SOP8 package.
