It is an easy-to-use, multi-functional 24 GHz millimeter wave radar sensor that does not require any external MCU for motion and distance detection, as well as angle measurement through light MCU calculations.

Features
· Easy to use
- "All-in-one" package to reduce system BOM
- Built-in autonomous motion and distance measurement functions, with I2C / SPI connection for setup and result acquisition
· Wide detection range
- Priority detection range: frontal 8m (* 1), FOV: 120deg (*1, *2)
- 2-channel receive antenna can be calculated by external MCU to achieve 2D angle detection
· 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
·Angle detection
Detects object angles by external MCU calculations and uses them for sector-level detection.
