The Hi-Link LD116 utilizes 24GHz Frequency Modulated Continuous Wave (FMCW) radar technology to detect micro-Doppler signatures from moving targets, specifically tuned for human presence. Its small 20mm x 15mm form factor houses a fully integrated RF front-end, signal processor, and digital output stage, providing a complete sensing solution.
This module excels in environments where passive infrared (PIR) sensors fail, as it is not influenced by ambient temperature, airflow, or visible light. It can detect movement through thin non-metallic barriers like acrylic, glass, and plastic, making it suitable for concealed installations. The LD116 is engineered for stability, with a phase noise of -96dBc/Hz at 1MHz offset and a receiver noise figure of 10dB, ensuring reliable operation in the presence of RF interference.
