AJMRTC LD2411S 24G Millimeter Wave Radar Sensor Module, 0.3~6m Human Ranging Detector, Ultra Low Power Microampere Radar Switch with Bluetooth APP Parameter Adjustment, 1 Piece for Smart Home Sensing

AJMRTC LD2411S 24G radar ranging sensor is a high-sensitivity human presence and micro-motion detection module adopting FMCW radar technology. It can detect moving human targets within 0.36m and capture subtle micro-motion such as breathing. With ultra-low microampere-level power consumption, it greatly extends the service life of battery-driven smart equipment. Built-in Bluetooth function allows users to configure all sensing parameters directly through mobile APP without rewriting firmware. Microwave signals can penetrate thin non-metallic barriers, and the sensing performance will not be disturbed by ambient brightness changes. It outputs stable serial data including distance and trigger status. It is widely used for smart light switches, human presence alarms, automatic door control, bathroom sensors and other smart home IoT automation projects.
