About this item

  • This sensor mainly uses the CCS811B chip. It is an ultra-low-power miniature digital gas sensor that can detect a wide range of volatile organic compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels.
  • Equivalent carbon dioxide (eCO2) is measured in the range of 400 to 8192ppm (parts per million), and various volatile organic compounds (TVOC) ranges from 0 to 1187ppb (parts per billion).
  • This sensor is very easy to set up and start working with. use it with an arduino to monitor the indoor or outdoor environment.
  • This sensor module is compatible for the arduino microcontrollers as well as raspberry pi etc.

3.0 out of 5 stars Dati troppo variabili.
Reviewed in Italy on 13 July 2020
Sensore molto compatto facile da configurare grazie alla breve documentazione su Wikipedia. Fornisce valori di CO2 e TVOC in dati seriali utilizzando il protocollo I2C. Il problema è che i dati risultano estremamente variabili. Consiglio di provarlo e di testarlo, magari avrete risultati diversi.
