• intros：{"brand_intro":"小米集团成立于2010年，由雷军创立，以'让每个人都能享受科技的乐趣'为使命。小米生态链覆盖智能家居、安防、健康等领域，通过'投资+孵化'模式打造了数百款爆品。在安防领域，小米依托米家APP强大的智能联动能力，将传感器、摄像头、门锁等设备无缝整合。其产品以高性价比、极简设计和易用性著称，品控遵循'严选'标准，核心元器件来自国际一线供应商。小米人体传感器2S作为生态链入门款，凭借超低价格和米家生态优势，成为年轻用户和租房族的首选。","product_intro":"小米人体传感器2S是米家智能家居生态的核心组件，主打'超低功耗'和'智能场景联动'。采用被动红外技术，探测距离7米，角度120度，可检测人体移动并触发灯光、空调、摄像头等设备自动化。内置CR2450纽扣电池，续航长达3年。通过蓝牙Mesh网关连接米家APP，支持设置'无人移动'超时报警、'有人经过'开灯等场景。相比传统红外探测器，它更侧重'智能触发'而非安防报警，适合用于玄关、走廊、卫生间等区域。竞品如Aqara人体传感器在探测精度上略胜一筹，但小米凭借价格和生态规模优势，销量遥遥领先。","key_specs":{"探测距离":"7米（25℃环境下）","探测角度":"水平120°，垂直60°","供电方式":"CR2450纽扣电池（续航约3年）","无线协议":"蓝牙Mesh（需搭配蓝牙网关）","工作温度":"-10℃~50℃","尺寸":"30×30×25mm（超迷你）"}}
