RCWL0516 Microwave Radar Sensor Switch Module Pack of 5 Short overview Pack of five RCWL0516 microwave radar motion sensor switch modules. Each module provides noncontact body induction detection with a typical range of 5 to 7 meters. The module accepts a wide operating voltage range and offers a digital output suitable for direct interfacing with control circuits. Key benefits Reliable motion detection without physical contact, reducing wear and allowing hands operation. Wide operating voltage range (4 to 28 V) for flexible use with common DC systems. Clear digital output with up to 100 mA drive capability for direct connection to relays, transistors, or control inputs. Pack of five modules lets you deploy multiple sensors across a project or modules as needed. Small PCB form factor simplifies integration into enclosures, fixtures, or custom electronics. Core features and specifications Model: RCWL0516 Function: microwave radar body induction motion sensor Detection distance: 5 to 7 meters Operating voltage: 4 to 28 V DC Output current: up to 100 mA Output type: digital motion switch signal suitable for control circuits Compatibility and integration Works with standard logiclevel microcontrollers and control boards. Compatible with DC systems within the 4 to 28 V range, including 5 V, 12 V, and 24 V setups. Small PCB module fits into custom housings and can be mounted in cabinets, fixtures, or frames for compact installations. Practical applications Automatic lighting control: trigger hallway, stairway, or closet lighting when motion is detected to improve convenience and energy use. Hands activation: use for touchless switches on appliances, bathroom fans, or vending equipment to reduce surface contact. Security and automation: integrate into alarm circuits or building automation systems to detect presence and initiate followup actions. What is included Five RCWL0516 microwave radar sensor switch modules Notes for use Ensure supply voltage is within 4 to 28 V DC. Observe the output current limit of 100 mA or use an external driver when switching higher loads. Mount modules away from large metal surfaces or shielding that could affect microwave sensing performance. This description reflects the specified model and its stated electrical and detection characteristics for practical project planning and integration.
