Adafruit SGP30气体传感器解决方案

Adafruit公司的SGP30是数字多像素气体传感器,采用Sensirion公司的CMOSens®技术,在单片上提供完整的传感器系统,包括数字I2C接口,温度控制的微加热板和两个预处理室内空气质量信号,从而提供更多空气质量的更详细信息.主要用在室内空气质量应用,空调, 空气净化器,智能家居和物联网 (IoT).本文介绍了SGP30气体传感器主要性能,功能框图,以及SGP30空气质量传感器分线板电路图和PCB设计图.
The SGP30 is a digital multi-pixel gas sensor designed for easy integration into air purifier, demand-controlled ventilation, and IoT applications. Sensirion’s CMOSens® technology offers a complete sensor system on a single chip featuring a digital I2C interface, a temperature controlled micro hotplate, and two preprocessed indoor air quality signals. As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP30 provides more detailed information about the air quality.
The sensing element features an unmatched robustness against contaminating gases present in real-world applications enabling a unique long-term stability and low drift. The very small 2.45 x 2.45 x 0.9 mm3 DFN package enables applications in limited spaces. Sensirion’s state-of-the-art production process guarantees high reproducibility and reliability. Tape and reel packaging, together with suitability for standard SMD assembly processes make the SGP30 predestined for high-volume applications.
