5 Pack RCWL0516 Microwave Radar Motion Sensor Modules Human Body Induction Switch Intelligent Sensor Overview These RCWL0516 microwave radar sensor modules detect human motion and provide a reliable switch output for automation and sensing projects. Each pack includes five identical modules for multipoint installation or spare parts. Key benefits Noncontact motion detection that reduces wear and false triggers from physical switches Easy to integrate with common microcontrollers and electronic control systems for fast project setup Pack of five modules provides consistent performance across multiple locations or for backup replacements Compact module format saves space in enclosures and simplifies mounting What it does and how it helps Detects human presence and movement using microwave radar technology for contactless switching Outputs a digital signal that can trigger lights, alarms, relays, or controllers without mechanical parts Helps automate lighting and security tasks, reduce manual switching, and streamline prototype development Main attributes Model: RCWL0516 Quantity: 5 modules per pack Form factor: compact PCB module suitable for tight spaces and easy mounting Function: motion and human presence induction with digital switch output Compatibility: works with common microcontrollers and control boards for DIY electronics and automation projects Performance: designed for responsive detection and stable switching behavior in typical indoor use Practical applications Automatic lighting control: trigger hallway, closet, or stairway lights when motion is detected to improve convenience and energy use Security and monitoring: add a motiontriggered input to alarm systems, entry detectors, or remote notifications for smallscale installations DIY electronics and robotics: use as a presence sensor for robots, interactive displays, or prototype automation tasks Integration tips Mount the module where it can sense the intended area without obstruction from large metal objects Route connections to a controller input to read the module output and implement desired switching logic Use multiple modules from the pack to cover larger spaces or create multizone detection layouts Why choose this module pack The RCWL0516 modules offer a practical, spaceefficient way to add reliable motion sensing to multiple projects. The fivemodule pack is ideal for developers, makers, installers, and educators who need consistent, readytouse sensors for automation, security, and prototyping.
