Fermion: ENS160 Air Quality Sensor - module with an air quality sensor

Digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels, intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device. SEN-14193

Air quality sensor module based on the SGP40 system. It uses CMOSens technology by Sensirion and provides information on the concentration of volatile organic compounds (VOC). Adafruit 4829

The SCD-40 CO2, temperature and humidity sensor module provides high accuracy readings. It is equipped with a Qwiic connector and communicates via an I2C interface. SparkFun SEN-22395

Module with SGP30 gas sensor. The sensor communicates via the I2C interface. SGP30 system contains several elements reacting to various metal oxides, which allows for more accurate determination of air quality. Adafruit 3709

Indoor air quality measurement module, combining two high-end Sensirion sensors – SCD41 and SEN55. It offers a comprehensive set of measurements, including CO2 concentration, volatile organic compounds (VOC), suspended dust (PM1.0, PM2.5, PM4, PM10), as well as temperature and relative humidity.
