24GHz 2D Detection model SC1233AR3

SC1233

SC1233AR3

“Easy-to-use” & “All-in-one” 24GHz radar sensor enabling motion & distance detection without any external MCU, and angle detection with light MCU calculations.

Features

  • ●Easy to use

    • System BOM can be reduced by “All-in-one” package radar sensor
    • Built-in autonomous motion/distance detection function enables only I2C/SPI
      connection for settings & result acquisition
  • ●Wide detection area with 2D detection

    • Preferable detection area: 8m(*1) in front direction, FOV: 120deg(*1)(*2)
    • 2RX antennas capable of 2D angle detection with external MCU calculation
  • ●Suited for battery operation

    • 0.5mW average operating power consumption on human detection application(*3)
    • After sensor setup & run, MCU can sleep until something detected
    • *1:Detection area depends on environmental condition
      *2:Half distance angle
      *3:In case of 0.1% duty cycle operation in Motion Detection mode

Example System Configuration

Example System Configuration

Example use case

●Entry Motion/ Presence Detection

Internal processing engine calculates & outputs Motion Detection (Entry Motion / Presence Detection) result through DETOUT.

  • [Entry Motion Detection]

    Entry Motion Detection
  • [Presence Detection]

    Presence Detection
  • ●Distance Detection

    Internal processing engine calculates & outputs
    Distance to the moving objects through I2C or SPI.

    Distance Detection
  • ●Angle Detection

    Angle of the detected object can be calculated in the ext.
    MCU,and be used for sector-level det.

    Angle Detection
