The mmWave radar technology detects micro-movements including breathing and typing, providing higher sensitivity than passive infrared sensors that require larger body movement to trigger.\u003c\/p\u003e\n\u003cp\u003eDesigned for offices, corridors, commercial spaces and residential rooms where hands-free lighting control is needed, the sensor offers 360° detection when ceiling-mounted and 180° coverage when wall-mounted. Detection range, time delay and ambient light sensitivity are all adjustable via dials on the sensor body: range scales from 25% to 100% of the maximum detection radius, time delay adjusts from 10 seconds to 15 minutes, and the light sensor can be set to prevent activation during daylight hours.\u003c\/p\u003e\n\u003cp\u003eThe white polycarbonate housing measures 93mm diameter with a 36mm projection when surface-mounted, or 28mm recess depth when fitted into a ceiling void. The sensor operates on 230V 50Hz mains and carries IP20 ingress protection for indoor dry locations. Operating temperature range is -20°C to +40°C, making it suitable for unheated storage areas and server rooms as well as standard commercial and residential environments.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e93mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e36mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e93mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e93mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e36°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e28mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/datasheet-OS0026W.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between mmWave and PIR sensors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003emmWave radar detects micro-movements like breathing and typing, whereas passive infrared (PIR) sensors require larger body movement to trigger.
