사물인터넷 시대의 시작

A symbolic image of the beginning of the IoT era. A living room at dusk, viewed from a slightly elevated angle. The room is modern and clean. On a coffee table, a smartphone displays a simple, glowing home control interface. Lines of light emanate from the phone, connecting to various home appliances like a lamp, a smart speaker, and a television, all of which are subtly illuminated. The atmosphere is calm, futuristic, and full of potential. The focus is on the connection and control, not the specific brand of the devices. The style should be a whimsical digital illustration, with a soft color palette and a playful, fantasy-like mood. Use clean lines, subtle textures, and dreamy lighting to create a sense of wonder and magical storytelling, suitable for a children's book cover.
