This is an easy-to-use all-in-one 24 GHz millimeter wave radar sensor for motion and distance detection without any external MCU.

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
System configuration example
Application Cases
· Entry range and status detection
Internal processing engine calculates and outputs motion detection (entry motion/status detection) results via DETOUT
· Distance detection
The internal processing engine calculates and outputs the distance to the moving object via I2C or SPI.
