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

Module with an analog MQ7 carbon monoxide sensor. It is powered with the voltage of 5 V and has an analog output. DFRobot SEN0132

The module with the natural gas and LPG concentration sensor (modMQ-5) allows the measurement of the concentration of natural gas, carbon monoxide, alcohol and methane. The module has an analogue output and an output triggered by exceeding the threshold of sensitivity.

Integrated gas sensor, pressure, humidity and temperature in the LGA-8 housing. Bosch Sensortec BME680

Module with BME680 for measuring the concentration of VOC, pressure, temperature and humidity. Equipped with a STEMMA QT connector, it communicates via I2C or SPI. Adafruit 3660

Module with sensors of environmental parameters. It allows you to measure temperature, humidity and pressure as well as CO2 and VOC concentration. DFRobot SEN0335

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 MQ-4 sensor allows methane concentration measurement. The measuring range of the sensor reaches up to 10,000 ppm and an analogue signal is obtained at the output.

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