AJMRTC HK-LD2410D-B 24G Millimeter Wave Human Presence Radar Module, 6M Motion & Static Perception Sensor, TTL Serial Communication, Bluetooth Parameter Adjustment, Smart Switch Test Kit C

AJMRTC HK-LD2410D-B human presence radar module adopts 24GHz FMCW millimeter wave technology. It can identify not only moving people but also subtle body movements and static human presence, which avoids the defect of traditional PIR infrared sensors that cannot detect stationary targets. It supports TTL serial communication to upload distance and presence status data. Integrated Bluetooth allows users to adjust sensing parameters via dedicated mobile APP. It comes as Test Kit C, ready for testing. Widely used for smart lighting, automatic door induction, smart home occupancy switch, office energy saving and IoT sensing projects. It works well with Arduino, ESP32 and other microcontrollers.
