<p><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">SGP40 是 Sensirion推出的数字 VOC(挥发性有机化合物)传感器,可轻松集成到空气处理设备和空气质量监测器中。</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">SGP40 基于 Sensirion 的 CMOSens® 技术, 数字 I²C 接口、由温度控制的微型加热板以及经湿度补偿处理的室内空气质量信号,能够在单个芯片上提供完整的传感器系统。</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">结合 Sensirion 强大的 VOC 算法(SGP40 VOC指数驱动程序包的一部分),传感器信号可直接用于室内空气质量评估,如触发空气处理设备的逐步风扇控制。</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">SGP40 将多像素和多热板方法提升到新高度,更加接近单独控制各个传感元件的目标,SGP40 还可大幅降低功耗,因此适用于电池驱动的应用。</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Sensirion 先进的生产流程可确保高度的可重复性和可靠性。最重要的是,SGP40符合RESET®与WELL™相关的健康建筑标准。</span></p>
