Hi-link HLK-LD016-5G Radar Sensor Module
The Hi-Link HLK-LD016-5G is a compact microwave radar sensor module operating in the 5GHz frequency band, engineered for motion detection and proximity sensing. Compared to traditional infrared or ultrasonic sensors, radar technology provides more precise and reliable detection, even in challenging environments.
Operating at 5GHz offers a major advantage by reducing interference from common 2.4GHz devices such as Wi-Fi routers, Bluetooth devices, and other household electronics. This makes the HLK-LD016-5G especially suitable for modern smart home, industrial, and IoT environments where RF congestion can affect sensor performance.
With a digital output, low power consumption, and compact design, the module can be easily integrated with Arduino, Raspberry Pi, ESP32, and other microcontrollers to enable motion-triggered automation, presence sensing, and safety systems.
