<p><span><span><span lang="ZH-CN">新款</span></span></span><span><span><span lang="EN-US">BME688</span></span></span><span><span><span lang="ZH-CN">是创新定制应用的理想选择</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">比如通过测量当前气体、跟踪温度和湿度的变化来检测食品变质或及时发现森林火灾。传感器的人工智能功能和</span>Bosch Sensortec</span></span><span><span><span lang="ZH-CN">全新的</span>BME AI-Studio</span></span><span><span><span lang="ZH-CN">软件工具，让客户可以直接针对自己的特定用例快速开发定制解决方案。为了进一步缩短上市时间，</span>Bosch Sensortec</span></span><span><span><span lang="ZH-CN">还提供兼容</span>Adafruit</span></span><span><span><span lang="ZH-CN">的开发套件。</span></span></span></p>

<p><span><span><span lang="ZH-CN">基于</span></span></span><span><span><span lang="EN-US">Bosch Sensortec</span></span></span><span><span><span lang="ZH-CN">成熟的</span></span></span><span><span><span lang="EN-US">BME680</span></span></span><span><span><span lang="ZH-CN">平台</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="EN-US">BME688</span></span></span><span><span><span lang="ZH-CN">内置的更新版本气体传感器可实现更广泛的测量范围</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN"><span>&nbsp;</span></span></span></span><span><span><span lang="ZH-CN">并拥有先进的人工智能功能。此气体传感器现可检测多种气体，包括挥发性有机化合物（</span>VOCs</span></span><span><span><span lang="ZH-CN">）、挥发性硫化合物（</span>VSCs</span></span><span><span><span lang="ZH-CN">）和其他类型的气体，如一氧化碳和氢气，检测范围为十亿分之一（</span>ppb</span></span><span><span><span lang="ZH-CN">）。</span></span></span></p>

<p><span><span><span lang="ZH-CN">“</span></span></span><span><span><span lang="EN-US">BME688</span></span></span><span><span><span lang="ZH-CN">将可靠的高精度传感器</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">与广泛的气体检测和创新人工智能功能结合在一起。</span></span></span><span><span><span lang="ZH-CN">”</span></span></span><span><span><span lang="EN-US">Bosch Sensortec</span></span></span><span><span><span lang="ZH-CN">公司首席执行官</span></span></span><span><span><span lang="EN-US">Stefan Finkbeiner</span></span></span><span><span><span lang="ZH-CN">博士说道</span></span></span><span><span><span lang="ZH-CN">，“</span></span></span><span><span><span lang="ZH-CN">这使我们的客户能够快速开发旨在改善健康、生活方式和可持续性的下一代应用。”</span></span></span></p>

<p><span><span><span lang="ZH-CN">例如</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">客户可能希望开发一种基于传感器的产品用以检测变质食物</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">而这就可以通过食物中细菌产生的</span></span></span><span><span><span lang="EN-US">VSCs</span></span></span><span><span><span lang="ZH-CN">来指示。此外同样可以根据细菌产生的</span>VSCs</span></span><span><span><span lang="ZH-CN">来检测口臭或体味。</span></span></span></p>

<p><span><span><span lang="ZH-CN">最佳的方法是直接在实地收集具有指示性的现实生活数据。例如</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">通过对新鲜和腐烂食物附近的气体进行采样</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">从而为既定空气样本中存在的</span></span></span><span><span><span lang="EN-US">VSCs</span></span></span><span><span><span lang="ZH-CN">建立不同的组合模型。</span>BME688</span></span><span><span><span lang="ZH-CN">在默认情况下能够非常准确地检测</span>VSCs</span></span><span><span><span lang="ZH-CN">，而</span>BME AI-Studio</span></span><span><span><span lang="ZH-CN">则能够针对其他气体混合物和应用进行优化。</span></span></span></p>

<p><span><span><span lang="ZH-CN">通过在现场而非实验室进行气体采样，新的检测设备所采用的衍生算法在评估实际情况时更加可靠。与气体数据一起，</span>BME688</span></span><span><span><span lang="ZH-CN">可同时测量湿度、气压和温度，并作为补充数据输入，以实现完整的人工智能建模。</span></span></span></p>

<p><span><span><span lang="ZH-CN">在我们的示例应用中</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">客户对这些大量数据进行分类</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">然后将其应用于</span></span></span><span><span><span lang="EN-US">BME AI-Studio</span></span></span><span><span><span lang="ZH-CN">中的人工智能模型开发中</span></span></span><span><span><span lang="ZH-CN">，</span></span></span><span><span><span lang="ZH-CN">即训练</span></span></span><span><span><span lang="EN-US">BME688</span></span></span><span><span><span lang="ZH-CN">识别食物上细菌生长明显迹象的能力。传感器训练完成后，最终的人工智能代码就会运行在客户终端产品的系统微控制器上。这种人工智能代码一般为轻量级，可以十分容易地运行在当前用于处理系统控制和管理任务的微控制器上。</span></span></span></p>

<p><span><span>BME688</span></span><span><span><span lang="ZH-CN">为对传感器尺寸和低功耗因素有高要求的移动和互联应用而开发。这款传感器封装紧凑，尺寸仅为</span>3.0 x 3.0 x 0.9 mm3</span></span><span><span><span lang="ZH-CN">。根据所需的数据速率和功能，电流消耗可配置在</span>2.1 µA</span></span><span><span><span lang="ZH-CN">和</span>11 mA</span></span><span><span><span lang="ZH-CN">之间，并通过</span>BME AI-Studio</span></span><span><span><span lang="ZH-CN">进行优化。</span></span></span></p>
