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.
