Motion sensor/detector mmWave HLK-LD2420

Product information:

The LD2420 is an extremely sensitive 24GHz millimeter wave radar module for detecting human presence, movement and micromovement. Thanks to FMCW technology and a built-in intelligent algorithm, this sensor is ideal for smart automation in indoor spaces such as offices, homes or home automation projects.

Detection principle: FMCW continuous wave radar

Application: Detection of movement and micromovement of persons

Detection range:
- No blind spot from 0.2 m
- Max. range up to 8 meters
- Detection angle: up to 60°

Output: UART & GPIO
Power: 3.3V (works between 3.0V – 3.6V)
Power consumption: average 50 mA
Dimensions: 20 × 20 mm
Installation: Flexible (ceiling, wall)
Adjustable: Detection distances, sensitivity, delay time

Plug & play with standard configuration, easily adjustable via supplied tooling. Perfect for presence detection without physical movement, such as in smart lighting, security or energy saving.
