Hi-Link HLK-LD017 5.8GHz Microwave Radar Motion Sensor Module | Low Power Human Presence Detection
The Hi-Link HLK-LD017 is a compact 5.8GHz microwave radar motion sensing module designed for reliable human motion and presence detection in low-power embedded applications. Using Doppler radar sensing technology, it detects movement by analyzing reflected microwave signals, delivering stable performance even under changing ambient light and environmental conditions. Similar modules in the Hi-Link 5.8GHz series are widely used in smart lighting, occupancy sensing, automation, and energy-saving control systems.
Unlike conventional PIR sensors, microwave radar sensing can provide more consistent detection performance in enclosed installations and is less affected by temperature, humidity, or environmental conditions. Its compact footprint and low power design make the HLK-LD017 suitable for integration into smart home devices, ceiling lights, occupancy sensors, and IoT products.
