LD2410S 24G Millimeter Wave Radar Module Human Presence Sensor Distance Detection Switch 3.3V 0.12mA Low Power 8m Motion 4m Presence Range ±60° Detection Angle 2.54 mm 5-Pin Serial GPIO UART Interface

Product Description:

LD2410S 24G millimeter-wave sensing module designed for indoor human presence sensing and distance detection. It detects motion, micro-motion, and stationary human presence while operating in a low-power mode with real-time detection result updates.

Core Selling Points:

Uses millimeter-wave distance measurement and low-power signal processing technology for human presence detection. Configurable sensing distance range, trigger and hold thresholds, data refresh rates for trigger and hold states, and unmanned reporting time support use in different intelligent scenarios and terminal products. Supports GPIO and serial communication functions.
