10PCS RCWL 0516 Microwave Radar Human Body Induction Sensor Modules What this product does and why you need it Accurate human motion detection using RCWL 0516 microwave radar technology. Detects body movement and converts it into an electronic switch signal for automated control. Eliminates manual switching and enables responsive, hands-free operation for lighting, security, HVAC, and more. Ten modules included so you can outfit multiple devices, stages of a project, or spare replacements without buying individual units. Key benefits Reliable detection: Microwave radar sensing provides stable performance across a range of conditions and is less affected by ambient light and temperature changes than some optical sensors. Fast response and high sensitivity: Quickly senses human activity within its detection range to trigger actions with minimal delay. Easy integration: Compact modules designed for straightforward incorporation into electronic projects and installations requiring human presence sensing. Cost-effective bulk pack: Ten identical modules simplify deployment across multiple locations or prototypes. Important attributes Model: RCWL 0516 microwave radar sensor modules Function: Human body induction switch module — outputs a switching signal when motion is detected Quantity: 10PCS per package Technology: Microwave radar for stable, contactless sensing Performance: High sensitivity and quick response within the module’s detection area Practical use scenarios Automatic lighting: Trigger indoor or outdoor lights on entry to save energy and improve convenience. Security and alarm systems: Detect unexpected movement to activate alarms or cameras in perimeter or room monitoring. Building automation and occupancy sensing: Control HVAC, ventilation, or smart devices based on presence to improve comfort and efficiency. How you can use it Use the module as a motion-triggered switch input for relays, lights, alarms, or microcontroller-based systems. Deploy multiple modules across a building or project for zoned presence detection with consistent behavior. Pack contents and suitability Ten RCWL 0516 microwave radar sensor modules, suitable for hobbyists, installers, and system integrators who need reliable human body induction sensing for multiple installations or projects.
