HLK-2410B Human Presence Radar Motion Detection Module (Pre-Soldered)

The HLK-2410B is a human presence radar motion detection module designed to sense occupancy and movement more reliably than simple PIR sensors, making it a strong choice for smart lighting, home automation, security alarms, interactive kiosks, and robotics projects. As a compact radar-based presence sensor, it helps systems detect when a person is nearby, remains in an area, or is moving, enabling responsive automation and reduced false triggering in indoor environments. Ideal for prototyping and embedded builds, this pre-soldered module is well suited to custom controllers and maker platforms including Arduino, ESP32, and Raspberry Pi.
