Features


· Easy to use

    -  "All-in-one" package to reduce system BOM

    -  Built-in autonomous motion and distance detection functions, with I2C / SPI connection for setup and result acquisition

· Wide detection range

    -  Priority detection range: Frontal 8m (* 1)

    -  120deg / 95deg selectable FOV(*1, *2) with Digital beam shaper

·Suitable for battery operation

    -  Average operating power consumption for human detection applications is 0.5mW (* 3)

    -  MCU can be put to sleep until a moving object is detected after setting up a running sensor

 

        *1: Detection area depends on environmental conditions

        *2:Half distance angle

        *3: Capable of operating at 0.1% duty cycle in motion detection mode
