AJMRTC HLK-LD2410C is a 24G FMCW millimeter-wave human presence radar module. It can identify stationary occupants and micro-motion such as breathing, which traditional infrared PIR sensors cannot detect. Built-in Bluetooth allows users to configure parameters via dedicated mobile APP without serial tools. It provides both UART ASCII data and GPIO level output. It works reliably in dark environments and is immune to most non-human interference. Widely used for smart lighting, smart switches, home automation, occupancy detection and IoT sensing projects.
