Hi-Link HLK-LD2411 24GHz Ranging Radar Sensor - Bluetooth Configurable Motion & Gesture
The Hi-Link HLK-LD2411 is a 24GHz FMCW radar sensor module designed for human presence detection, ranging, and gesture recognition. Operating on a 5V supply, it provides configurable GPIO outputs ideal for integration with microcontrollers (Arduino, ESP32, STM32) and industrial PLCs for automated control applications.
Features
- 24GHz FMCW radar for precise human presence and distance sensing up to 2 meters.
- Integrated gesture recognition for lift/release and approach/retreat movements.
- Bluetooth-enabled configuration for adjustable sensing distance and parameters.
- Wide detection coverage with a horizontal angle of ±20° and vertical angle of ±40°.
- Robust operating temperature range from -40°C to +85°C for harsh environments.

The HLK-LD2411 employs Frequency Modulated Continuous Wave (FMCW) radar technology at 24GHz to detect human presence, measure distance, and recognize simple gestures. This non-contact sensing method provides high reliability and privacy compared to optical solutions, functioning effectively in various lighting conditions.
The module features a configurable antenna pattern, allowing the beam to be optimized for specific applications, such as a narrow horizontal beam for toilet lid automation to prevent false triggers from passersby. It outputs digital GPIO signals based on detected events, enabling direct control of actuators or integration into larger control systems via common microcontrollers or PLCs.
