VOC传感器SGP30 / SGPC3
适用于暖通空调和室内空气质量应用
SGPxx 是一个数字化多像素气体传感器平台，专为轻松集成到空气净化器、按需新风控制和物联网应用中而设计。
SGP30 设计用于智能家居、家电和物联网应用。它提供两个经过校准的空气质量信号和片上湿度补偿功能。此外，Sensirion 还通过 SGPC3 为移动应用提供低功率的可靠气体传感解决方案。
Sensirion 的 CMOSens® 技术在单个芯片上提供完整的传感器系统，该系统采用一个数字化 I2C 接口、一个温度控制的微加热器和两个经过预处理的室内空气质量信号。作为首款在单个芯片上采用多个传感元件的金属氧化物气体传感器，SGP3x 可提供有关空气质量的更详细信息。针对现实世界存在的污染气体，该传感元件具有无与伦比的可靠性，可以实现独一无二的长期稳定性和低漂移。极小的 2.45 x 2.45 x 0.9 mm3 DFN 封装支持在有限的空间中应用。Sensirion 的先进生产工艺保证了高度的可再现性和可靠性。胶带和卷轴封装加上标准 SMD 装配工艺的适宜性，使得 SGP30 注定适合大规模的应用。
