Fresh lifestyle product photography of a smart plant care sensor on a bright kitchen windowsill beside a healthy potted herb plant. The device is a small matte white pebble-shaped sensor with a slim brushed brass soil probe, partly inserted into the soil, with one spare sensor lying nearby and a simple phone mockup showing only abstract shapes with no readable UI. Vertical 3:4 composition, clean domestic gardening scene, product scale clearly visible, water droplets on leaves, terracotta pot and natural soil texture. Bright morning window light, fresh green reflections, crisp soft shadows, premium smart-home gardening mood, no logos, no readable text, no watermark, no fake interface writing.
