It's designed to plug directly into the \u003ca href=\"https:\/\/zaitronics.com.au\/collections\/seeed-studio-xiao-boards\"\u003eSeeed Studio XIAO series\u003c\/a\u003e, giving you a compact presence sensor for smart home, automation, and occupancy-detection projects.\u003c\/p\u003e\n\u003ch2\u003eFMCW-Based Radar Sensing\u003c\/h2\u003e\n\u003cp\u003eThe sensor uses the FMCW (Frequency-Modulated Continuous Wave) principle, giving it high sensitivity while remaining resistant to environmental interference that can trip up simpler PIR-based motion sensors.\u003c\/p\u003e\n\u003ch2\u003eDetects Both Movement and Stillness\u003c\/h2\u003e\n\u003cp\u003eUnlike standard motion sensors, this board detects moving human bodies with high sensitivity while also picking up static individuals, micro-movements, and people who are sitting or lying down. That makes it well suited to occupancy sensing in spaces where someone might be present but not actively moving.\u003c\/p\u003e\n\u003ch2\u003eWide Detection Range\u003c\/h2\u003e\n\u003cp\u003eWith a field of view up to 60 degrees and a detection range of up to 5 meters, the sensor covers a broad area from a single mounting point, useful for room-level presence detection rather than a narrow single-target zone.\u003c\/p\u003e\n\u003ch2\u003eFlexible Parameter Adjustment\u003c\/h2\u003e\n\u003cp\u003eDetection parameters can be tuned over Bluetooth or a serial connection to suit different environments and scenes, or configured directly through an app without needing a serial connection at all.\u003c\/p\u003e\n\u003ch2\u003eDiscreet Shell Penetration\u003c\/h2\u003e\n\u003cp\u003eThe sensor has good penetration through non-metallic enclosures, so it can be mounted inside a product's casing without needing a visible cutout or perforation.\u003c\/p\u003e\n\u003cp\u003eNote that this board isn't directly compatible with the XIAO nRF54L15 series, since Arduino isn't currently supported on that board. The hardware interface itself is fully compatible, so developers can manually adapt the software if needed, and official software support from Seeed Studio is in development.\u003c\/p\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e24GHz mmWave Sensor for XIAO board\u003c\/li\u003e\n\u003cli\u003e2x 7-pin female headers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Frequency\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24GHz to 24.25GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDC 3.3V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Supply Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;200mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAverage Operating Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e79mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModulation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFMCW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTarget Application\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHuman presence sensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDetection Distance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.75m to 6m, adjustable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDetection Angle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e±60°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDistance Resolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.75m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSweep Bandwidth\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-40°C to 85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18mm x 22mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eHardware Overview \/ Pinout\u003c\/h2\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/1_84_1024x1024.webp\" alt=\"24GHz mmWave Human Static Presence Sensor for XIAO hardware overview and pinout\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/24GHz_mmWave_for_XIAO-Datasheet-V1.00.pdf\"\u003eUser Manual\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/24GHz_mmWave_for_XIAO-Usermanual-V1.00.pdf\"\u003eUser Protocol Manual\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/24GHz-mmWave-for-xiao-SCH.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eBrowse our full range of \u003ca href=\"https:\/\/zaitronics.com.au\/collections\/seeed-studio-xiao-boards\"\u003eXIAO Development Boards\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seeed Studio","offers":[{"title":"Default Title","offer_id":56000413335844,"sku":"SS101010001","price":9.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/1-101010001-seeed-studio-24ghz-mmwave-for-xiao-45font_1_1.jpg?v=1786351626","url":"https:\/\/zaitronics.com.au\/products\/24ghz-mmwave-human-static-presence-sensor-for-seeed-studio-xiao","provider":"Zaitronics","version":"1.0","type":"link"}
