Product Description
HLK-LD2460 is a 24GHz millimeter wave radar product for human perception, with distance angle test function. It consists of 1-transmitter and 2-receiver millimeter wave radar chips, high-performance microstrip antenna, high-performance MCU, high-performance Bluetooth SOC and peripheral auxiliary circuits. It uses FMCW waveform to accurately identify 3-5 human targets and estimate the location of the targets. This product can be used in scenes such as home, office, hotel, etc. to achieve accurate sensing of multiple moving, micro-moving or stationary human bodies.
