描述
Grove – HCHO Sensor 甲醛氣體感測器
Grove HCHO 甲醛傳感器是一種半導體VOC氣體傳感器。其設計基於WSP2110，其電導率隨空氣中VOC氣體濃度而變化。通過電路，電導率可以轉換成對應於氣體濃度的輸出信號。該傳感器可以檢測濃度高達1ppm的氣體。適用於檢測甲醛，苯，甲苯等揮發性成分。本產品可用於檢測家庭環境中的有害氣體。因此，這是您提高室內環境生活質量的好幫手。
注意事項: 傳感器值只反映在允許的誤差範圍內近似的氣體濃度趨勢，但並不代表確切的氣體濃度。空氣中某些組分的檢測通常需要更精確和更昂貴的儀器，這不能用單個氣體傳感器來完成。如果您的項目旨在獲得非常精確的氣體濃度，那麼我們不建議使用這種氣體傳感器。

The Grove – HCHO Sensor is a semiconductor VOC gas sensor. It uses the VOC sensor WSP2110 whose conductivity changes with the concentration of VOC gas in air. With a circuit, the conductivity can be converted to an output signal that corresponds to the gas concentration. This sensor has a very high sensitivity and stability, it can detect the gas whose concentration is up to 1ppm. It can be used to detect Toluene, Methanal, Benzene, Alcohol, Acetone etc. This product can be used to detect the presence of harmful gas in the home environment. It can be a good assistant to improve indoor air quality. Specification
