HLK-LD2420

1.product introduction

HLK-LD2420It is a high-performance24GHzA radar module with a send-and-receive antenna. Its human body sensing algorithm uses millimeter wave

Radar distance measurement technology andS3The advanced proprietary signal processing technology of the series chips realizes the precise perception of motion, micro-movement and standing human body.

HLK-LD2420It is mainly used to detect whether there is a moving or slightly moving human body in the indoor scene perception area, and refresh the detection results in real time. it's right

The farthest sensing distance of moving human body is8 meters, can easily configure the sensing distance range, sensing sensitivity and refresh time in different intervals, support

GPIOsandUARTInterface, plug and play, flexibly applied to different intelligent scenarios and terminal products.
