24GHz 2D Detection model 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.
SC1233AR3
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 use case
Entry Motion/ Presence Detection
Internal processing engine calculates & outputs Motion Detection (Entry Motion / Presence Detection) result through DETOUT.
[Entry Motion Detection]
[Presence Detection]
Distance Detection
Internal processing engine calculates & outputs
Distance to the moving objects through I2C or SPI.
Angle Detection
Angle of the detected object can be calculated in the ext.
MCU,and be used for sector-level det.
