Figaro TGS2602 - air quality sensor

ENS160 gas sensor module to measure the concentration of carbon dioxide (eCO2) and volatile organic compounds (TVOC) in the air. It communicates via an I2C or SPI interface. SparkFun SEN-20844

Module dedicated to projects related to air quality monitoring. It uses the popular ENS160 and BME280 chips and provides a variety of environmental data such as Air Quality Index (AQI), TVOCs levels, CO2 equivalent (eCO2), atmospheric pressure, humidity and temperature. It communicates via the I2C interface and offers two Qwiic connectors. SparkFun SEN-22858

BME688 integrated gas, pressure, temperature and humidity sensor module in a single MEMS housing. It is equipped with an I2C and SPI interface. It has built-in AI functions. Waveshare BME688 Environmental 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

The sensor is designed for indoor air quality testing. The main gas detected is carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases. It is compatible with 5V and 3.3V power supply. Seeed Studio 101020078
