LD2410B millimeter wave human presence radar module adopts FMCW radar technology, which can identify static sitting, lying and subtle human micromotion that PIR infrared sensors cannot capture. It provides GPIO digital level output and UART serial communication output at the same time, convenient to connect with single-chip microcomputer, development board and smart host. The sensing distance, detection delay, trigger threshold and other parameters can be modified via BLE wirelessly. It is widely used in smart home human induction lamp, automatic switch, cabinet sensor, home assistant and ESP
