Unlike conventional PIR sensors, it uses microwave radar technology to detect movement through plastic, glass, and other non-metallic materials, providing higher sensitivity, faster response, and reliable performance in both daylight and complete darkness.\u003cspan class=\"PDq2pG_selectionAnchor\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"\" data-end=\"1659\" data-start=\"996\"\u003eOperating from a wide 4V–28V DC input, the RCWL-0516 outputs a stable digital signal whenever motion is detected, making it easy to interface with Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers. Its 360° detection capability, low power consumption, compact size, and dependable performance make it an excellent choice for smart lighting, home automation, security systems, occupancy detection, IoT devices, robotics, automatic doors, and industrial automation. Whether you're building DIY electronics or professional embedded systems, the RCWL-0516 offers a reliable, cost-effective, and easy-to-integrate motion sensing solution.\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eSpecification:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: RCWL-0516 \u003c\/li\u003e\n\u003cli\u003eType: Microwave Radar Sensor \u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 4-28V\u003c\/li\u003e\n\u003cli\u003eOperating Current: 2.8mA (typical); 3mA (max)\u003c\/li\u003e\n\u003cli\u003eDetection Distance: 5-9m\u003c\/li\u003e\n\u003cli\u003eTransmitting Power: 20mW (typical); 30mW (max)\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: 3.2-3.4V\u003c\/li\u003e\n\u003cli\u003eOutput Voltage Driving Capacity: 100mA\u003c\/li\u003e\n\u003cli\u003eTrigger Way: repeat trigger\u003c\/li\u003e\n\u003cli\u003eOutput Control Low Level: 0V\u003c\/li\u003e\n\u003cli\u003eOutput Control High Level: 3.3V\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -20~80 celsius\u003c\/li\u003e\n\u003cli\u003eStorage Temperature: -40~100 celsius\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0618\/9042\/9095\/files\/New_Project_7_bf3c0b5c-0adb-4de9-9277-4654b4b1e85c.jpg?v=1736927070\" alt=\"\"\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eFeatures:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli data-end=\"251\" data-start=\"149\" data-section-id=\"k5de0p\"\u003eMicrowave Radar Motion Detection detects human movement using 3.2 GHz Doppler radar technology.\u003cspan class=\"PDq2pG_selectionAnchor\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-end=\"339\" data-start=\"252\" data-section-id=\"13ls9k0\"\u003eWide Operating Voltage Supports 4V–28V DC input for versatile applications.\u003c\/li\u003e\n\u003cli data-end=\"449\" data-start=\"340\" data-section-id=\"l76gpi\"\u003eNon-Contact Motion Sensing Detects movement through plastic, glass, and other non-metallic materials.\u003c\/li\u003e\n\u003cli data-end=\"541\" data-start=\"450\" data-section-id=\"m696mo\"\u003eLong Detection Range Senses motion up to 5–7 metres (depending on environment).\u003c\/li\u003e\n\u003cli data-end=\"615\" data-start=\"542\" data-section-id=\"bxxyg8\"\u003e360° Detection Coverage Wide-angle detection with no blind spots.\u003c\/li\u003e\n\u003cli data-end=\"702\" data-start=\"616\" data-section-id=\"33fl34\"\u003eLow Power Consumption Ideal for battery-powered and energy-efficient projects.\u003c\/li\u003e\n\u003cli data-end=\"810\" data-start=\"703\" data-section-id=\"1k3pq17\"\u003eDigital Output Signal Easy interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers.\u003c\/li\u003e\n\u003cli data-end=\"909\" data-start=\"811\" data-section-id=\"xx47e7\"\u003eCompact \u0026amp; Lightweight Design Small PCB for easy installation in DIY and embedded projects.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003ePin Description:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3V3: 3V3 power output\u003c\/li\u003e\n\u003cli\u003eGND: Ground\u003c\/li\u003e\n\u003cli\u003eOUT: Control output: when detecting moving objects, it will output a high level.\u003c\/li\u003e\n\u003cli\u003eVIN: Input voltage, 4-28V\u003c\/li\u003e\n\u003cli\u003eCDS: Enable control chip, lower than 0.7V, OUT will output low level all the time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eAdjustment Part Introduction:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eC-TM: Adjust repeat trigger time; the default trigger time is 2s.
