LD2411/ LD2411S/LD2410S/LD2420 mmWave 24G Radar Ranging Distance Detection Radar Sensor Module

LD2410S is a low-power human presence detection millimeter wave radar sensor. The hardware is equipped with an AloT millimeter wave sensor, a high performance 24GHz one-transmitter-one-receiver antenna and peripheral circuits; The low-power intelligent body sensing algorithm utilizes millimeter-wave sensor distance measurement technology and the ICL 1112 chip proprietary radar signal processing and low-power control technology. Realize accurate sensing of motion, micro-motion and standing human body.

LD2411S is a 24GHz ranging radar sensor module, the working principle is to utilize the FMC W FM continuous wave. The working principle is to use FMC W FM continuous wave to detect the target in the set space, combined with radar signal processing, accurate sensing algorithms. Accurately senses the distance and status information of micro-motion/movement objects.

Configuration tools are available to modify the sensing distance range, sensing sensitivity and delay time.
