描述

SparkFun SGP40 空氣品質感測器 – SGP40 (Qwiic) 高精度 TVOC 感測器

SparkFun SGP40 空氣品質感測器 可測量您房間或房屋中的空氣質量。SGP40 基於 Sensirion 的 CMOSens ®技術,使用金屬氧化物 (MOx) 傳感器和溫控微加熱板,並提供基於濕度補償的揮發性有機化合物 (VOC) 的室內空氣質量信號。傳感元件和 VOC 算法均具有無與倫比的穩健性,可抵禦現實世界應用中存在的污染氣體,從而實現獨特的長期穩定性以及低漂移和設備間差異。

SGP40 不會返回特定濃度或 VOC 氣體。相反,它根據室內環境中存在的常見 VOC 氣體輸出一個數字值,並且該值可以與 Sensirion 的 VOC 指數算法相結合,以檢測與 24 小時內平均讀數相關的 VOC 事件的相對強度。將 SGP40 視為用於檢測房間內 VOC 的靈敏電子鼻。

文件與資源

The SparkFun SGP40 Air Quality Sensor provides a measurement of the quality of the air in your room or house. The SGP40 is based on Sensirion’s CMOSens® technology and uses a metal oxide (MOx) sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound (VOC) based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.

The SGP40 does not return specific concentrations or VOC gases. Instead, it outputs a digital value based on common VOC gases present in an indoor environment and this value can be combined with Sensirion’s VOC Index Algorithm to detect the relative intensity of VOC events in relation to the average readings in a 24hr period. Think of the SGP40 as a sensitive electronic nose for detecting VOCs in a room.
