Figaro TGS2602 - 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

Module with gas sensor designed to monitor indoor air quality. It was based on the AMS CCS811 system that allows the detection of volatile organic compounds (VOCs) in the air. Digilent 410-386

Air quality sensor module based on the ENS160 system. It communicates via the I2C interface (Gravity connector). DFRobot SEN0514

PM2.5 dust sensor powered by 5V, communication via the UART interface. Sharp GP2Y1051AU0F

Module with air quality sensor SGP30. It allows you to read the concentration of VOC (TVOC) and eCO2 and communicates via the I2C interface. Pimoroni PIM480

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

Compact MEMS environmental sensor capable of measuring temperature, humidity, pressure and VOC, with I2C and SPI support and AI-powered gas analysis. Ideal for projects such as weather stations, smart home systems and air quality monitors, it provides high measurement precision and integration flexibility. DFRobot SEN0617

Laser dust sensor is a digital universal particle concentration sensor,it can be used to obtain the number of suspended particulate matter in a unit volume of air within 0.3 to 10 microns, namely the concentration of particulate matter, and output with digital interface, also can output quality data of per particle. DFRobot SEN0177

Digital sensor dedicated to measuring carbon dioxide (CO2), air temperature and relative humidity. High performance, fast response and excellent stability make it an ideal solution for a variety of applications such as greenhouses, cities, poultry farms and transport stations. Seeed Studio 101991029

Laser sensor of air pollution with particles PM1,0, PM2.5 and PM10. It allows for precise analysis of the amount of pollutants in the environment, has small dimensions and a built-in silent transfer fan. Data is output to the UART interface. PMS3003

Air quality sensor module PMSA003. It allows you to analyze the amount of pollutants based on the concentration of PM1.0, PM2.5 and PM10 particles. SB Components 21208

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.
