5V HLKLD1115H Mini 24G Human Presence Sensor Micro Motion Radar Module Compact radarbased presence detection for reliable occupancy sensing and motiontriggered control. Designed for easy integration with 5V systems, this mini micro motion radar module detects very small movements and provides a practical alternative to traditional motion sensors. Key benefits Detects small and slow movements that passive sensors can miss, enabling reliable presence detection in dim or stationary conditions. Operates from a 5V supply for direct compatibility with common 5V microcontrollers and control boards. Small, lowprofile module fits into tight spaces and can be mounted inside devices, fixtures, or control panels. Radarbased sensing works without visible light and does not require direct line of sight to the subject, allowing more flexible placement. Simple integration into automation, security, and lighting systems for occupancybased control or trigger functions. Main features 24G micro motion radar for human presence detection and motion sensing. 5V operating voltage for straightforward use with common development boards and controllers. Miniature, PCB module form factor for spaceconstrained applications. Stable performance for motiontriggered switching and presence monitoring. Compatibility and integration Designed for direct use with 5V logic systems and microcontrollers. Can be integrated into smart lighting, HVAC, security, and automation projects to add presence awareness. Suitable for use with controllers that accept digital input or can read the module output through a small interface. Practical applications Smart lighting control: turn lights on when a person is present and off when a space is vacant, improving convenience and reducing manual switching. Building automation and HVAC: enable presencebased ventilation or temperature control to respond to actual occupancy. Security and access control: detect unauthorized presence in areas where PIR sensors are less effective, or add an additional detection layer to existing systems. Why choose this module Reliable detection of micro movements for situations where traditional motion sensors fail. Compact and easy to integrate into a wide range of electronics projects and commercial installations. Works in low light and can be positioned without strict lineofsight requirements. Notes for installers and developers Requires a stable 5V supply and a compatible interface to read the module output. Typical mounting inside fixtures or enclosures improves aesthetics and protects the module while keeping detection effective. Test placement and orientation during installation to achieve the desired detection coverage for each application.
