HLK LD2410 mmWave - 24GHz Human Presence Sensor Kehadiran Manusia - No Cable

This high-sensitivity 24GHz human presence sensing radar module utilizes FMCW (frequency-modulated continuous wave) to detect human targets in the set space. Combined with radar signal processing and accurate human sensing algorithm, it can achieve high-sensitivity sensing of human presence status, which can identify human body in motion and stationary state and calculate auxiliary information like the distance to the target.

The sensing effect of the radar module is insusceptible to environmental factors like temperature, brightness, humidity, light fluctuations, etc. Besides, FMCW radars can penetrate materials, which enables this module to work well in a shell without opening holes.

This microwave radar is mainly used in indoor scenarios to sense whether there is a moving or micro-moving human in the detection area and output the detection results in real time. It offers a sensing distance of up to 6 meters and a resolution of 0.75m. Besides, it provides serial communication protocol so users can configure the sensing distance range, sensing sensitivity in different intervals, and delay time for different applications.
