5pcs 5.8GHz Microwave Radar Sensor Modules Compact DC 3.3V to 20V intelligent trigger sensor switches for motion and presence detection Product overview These five identical microwave radar sensor modules operate at 5.8GHz and accept a wide DC supply range from 3.3V to 20V. Each module is a compact PCBmounted sensor designed to deliver reliable intelligent trigger signals for automation, lighting, security, and embedded projects. Key benefits Flexible powering: Wide input range DC 3.3V to 20V lets you use common microcontroller supplies, battery packs, or regulated power rails without extra converters. Reliable detection: 5.8GHz microwave operation penetrates nonmetallic obstructions and detects motion or presence even in low light, making the modules suitable for indoor automation and sensing tasks. Plug and integrate: Small PCB modules are ready to wire into existing control circuits, relay modules, LED drivers, or microcontroller projects for quick prototyping and deployment. Multiple quantity: Pack of five modules supports multizone installations or spare parts for ongoing projects. What it does Detects motion and provides an intelligent trigger output that can drive switching circuits or signal processing units. Operates across a broad DC voltage range, reducing power supply constraints and simplifying integration with varied hardware. Designed for use as a sensor input for automatic switching, occupancy sensing, and triggerbased controls. Compatibility and integration Power: DC 3.3V to 20V Frequency: 5.8GHz microwave radar Interfaces: Simple wiring for power and trigger output suitable for relays, transistors, optocouplers, or direct microcontroller inputs (observe input thresholds and protection requirements) Physical: Compact PCB module form factor suitable for mounting inside housings or control panels Materials and build Standard PCBmounted electronic components and antenna structure designed for lowprofile installation and repeated use. Lightweight and compact to fit into small enclosures or behind panels. Performance highlights 5.8GHz radar enables motion detection through nonmetallic obstructions and under varied lighting conditions. Wide voltage tolerance improves resilience to supply variations and accommodates a range of control systems. Typical applications Automatic lighting control: Use the sensor to turn lights on or off in hallways, closets, or stairwells when motion is detected. Security and access: Trigger alarms, door openers, or notification systems when presence or movement is detected near an entry point. Embedded projects and automation: Integrate with microcontrollers, relay boards, or home automation controllers to add motiontriggered actions to prototypes and finished products. What you get Five identical 5.8GHz microwave radar sensor modules, each rated for DC 3.3V to 20V operation and ready for integration into your control circuits. Notes for installers Verify wiring polarity and observe recommended input protections for sensitive logic inputs. Performance can vary with installation geometry and surrounding materials; allow space between the sensor and large metallic surfaces for detection.
