The HLK-LD2452 utilizes Frequency-Modulated Continuous Wave (FMCW) radar technology in the 24GHz ISM band to detect motion, distance, and angle with high accuracy. Its advanced signal processing algorithms enable it to distinguish and track up to three targets in real-time, providing precise coordinates and velocity data. This makes it far superior to basic PIR sensors for applications requiring detailed spatial awareness.
Engineered for industrial-grade reliability, the module operates across an extended temperature range from -40°C to 85°C. Its compact 23 x 42 mm form factor and 1T2R antenna configuration are optimized for integration into space-constrained designs. The module outputs processed data via a serial UART interface, simplifying integration with host systems for immediate use in automation logic.
