AJMRTC LD2410B 24GHz Millimeter Wave Human Presence Radar Sensor Module, Smart FMCW Radar Detector with GPIO & UART Output, Static Micro-Motion Detection Module Only for Smart Home DIY

AJMRTC LD2410B millimeter-wave radar module adopts FMCW 24GHz radar technology, which outperforms traditional PIR infrared sensors. It can capture not only walking motion but also static human presence and subtle micromovements such as breathing. It provides two mainstream output modes: GPIO high/low level for simple trigger control and UART TTL serial port for reading distance and status data. You can customize detection range, zone sensitivity and hold delay by supporting configuration software or mobile APP. It is not affected by ambient light, shadow or curtain obstruction. This listing sells the radar module only, without brackets, power adapters or extra accessories. Perfect for smart light switches, home automation, access control, cabinet lighting triggers, Arduino, ESP32, Raspberry Pi and other IoT embedded projects.
