24GHz Radar Sensor Module with Human Detection

The HLK-LD2410C is a high-sensitivity 24GHz human presence status sensing module. It uses FMCW (frequency-modulated continuous wave) to detect human targets in the set space. Combined with radar signal processing and accurate human body sensing algorithms, it has a high-sensitivity human presence status sensing, and can identify human bodies either moving or stationary. Additional information such as the distance to the target can be calculated.

This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area and output the results in real time. The sensing distance can reach up to 5 meters, and the distance resolution is 0.75m. The LD2410C can be easily configured for the sensing distance range, sensing sensitivity in different intervals and unmanned delay time, etc., to adapt to different specific application needs. This makes it ideal for use in many IoT "smart home" applications.
