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。


  • 工作電壓:5.0V±0.3V
  • 目標氣體:甲醛,苯,甲苯,酒精
  • 濃度範圍:1〜50 ppm

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
