KEYESTUDIO CCS811 Carbon Dioxide CO2 VOCs Air Quality Gas Sensor Module for Arduino

Ratings for KEYESTUDIO (CPR Score)

Features

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).
