HLK-LD2410C Human Presence Radar Sensor 24GHz

HLK-LD2410C is a high-sensitivity 24GHz radar module designed for accurate human presence detection. It uses FMCW (continuous wave radar) technology to detect both moving and stationary objects and determine distance in real time.

The module is intended for indoor use and is widely applied in smart home systems, lighting automation, and security solutions. Supports flexible configuration via app or UART, allowing users to adjust detection zones and sensitivity. Often selected among electronic components when comparing price, reviews, and functionality before users buy.
