It connects through Wi-Fi or ZigBee protocol to the Graffiti ecosystem, allowing automatic settings that link lights, switches, sockets and curtains via the Graffiti or Smart Life app on Android and iOS. Powered continuously by a USB cable at 5V 2A, it suits smart home setups where ongoing presence monitoring is needed. The unit is black, measures 10 x 10 x 4 cm, and is designed for fixed installation. For accurate operation, use a quality 5V 2A charging head and avoid aiming the device at appliances such as air conditioners, refrigerators, computers or fans. Because the radar is omnidirectional, it can detect people up to 1.5 metres behind the device, so the back should be positioned against a wall. Fixing the sensor securely helps prevent loosening and maintains consistent performance. This product is intended for indoor smart home use where linkage with other Graffiti-compatible devices is required.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black 24G millimeter wave human presence sensor, 10x10x4cm, Wi-Fi ZigBee, USB powered smart home detector\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/3633\/2025-10-16\/original-image\/1cdd151e-04cd-491b-92d8-034be75e4424.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe sensor uses 24G millimeter wave radar for real-time human presence detection, with Wi-Fi or ZigBee connection options.
