Gas & Air Quality Sensors

SKU: AF-4867 | Brand: Adafruit

The Adafruit SCD-30 is a true NDIR (Non-Dispersive Infrared) CO2 sensor that directly measures carbon dioxide concentration in ambient air, rather than estimating it from volatile organic compounds. With an integrated...

SKU: DF-SEN0219 | Brand: DFRobot

The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, there's a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 ...

SKU: SF-SEN-22396 | Brand: SparkFun

This SparkFun CO2 Humidity and Temperature Sensor features the next-generation SCD41 photoacoustic CO2 sensor for high-accuracy environmental readings. The SCD41 uses Sensirion's PASens® photoacoustic measurement syst...

SKU: DF-SEN0220 | Brand: DFRobot

The Gravity UART Infrared CO2 Sensor uses non-dispersive infrared (NDIR) technology to measure carbon dioxide concentrations from 0 to 50,000 ppm. It offers excellent selectivity with no oxygen dependency, built-in te...

SKU: AF-6331 | Brand: Adafruit

The Adafruit SEN6x Breakout lets you quickly connect a Sensirion SEN66 (or other SEN6x) environmental sensor node to any microcontroller or single-board computer via STEMMA QT / Qwiic — no soldering or breadboarding r...

SKU: EF-EF05030 | Brand: ElecFreaks

The gas sensor is an essential sensor for environmental detection. The ELECFREAKS PlanetX CO2 Sensor is designed to detect the concentration of CO2 with high sensitivity. The higher the concentration of CO2 is, the sm...

SKU: SF-SEN-22395 | Brand: SparkFun

The SparkFun SCD40 breakout board measures CO₂ concentration, humidity, and temperature using Sensirion's PASens photoacoustic measurement technology. The sensor detects CO₂ from 0 to 40,000 ppm with high accuracy ove...

SKU: SF-SEN-15112 | Brand: SparkFun

The SCD30 from Sensirion is a high quality Nondispersive Infrared (NDIR) based CO₂ sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature an...

SKU: DF-SEN0659 | Brand: DFRobot

This industrial CO2 probe is built for reliable carbon dioxide monitoring in environments such as indoor air quality systems, pipelines, greenhouses and fresh air systems. It uses NDIR sensing to measure CO2 from 400 ...
