Object Detection Device
Abstract: The object detection device includes: a pyroelectric element configured to output a current signal in response to a change in an amount of infrared light; an I/V conversion circuit including an operational amplifier a capacitive element serving as a feedback circuit and a discharging circuit and configured to convert the current signal to a voltage signal; an A/D conversion circuit configured to convert the voltage signal to a first digital signal; a digital filter configured to extract a detection component having a frequency included in a frequency band associated with an object from a waveform represented by the first digital signal by subjecting the first digital signal to an arithmetic processing and create a second digital signal representing a waveform of the detection component; a determination circuit for detecting the target object on the basis of the second digital signal; and a control unit for controlling the discharge circuit on the basis the cycle corresponding to a predetermined frequency less than or equal to the lower limit of the frequency band and discharging charge stored in the capacitor element.
