Gas & Air Quality Sensors

SKU: DF-FIT0227 | Brand: DFRobot

The MQ7 is a simple-to-use Carbon Monoxide (CO) sensor suitable for detecting CO concentrations in the air. It offers a wide detection range from 20 to 2000 ppm, making it ideal for safety monitoring and air quality p...

SKU: SF-BOB-08891 | Brand: SparkFun

This breakout board provides a convenient PCB adapter for MQ-series gas sensors (MQ-3, MQ-4, MQ-6, MQ-7, and MQ-8). It converts the sensor's oversized, oddly-spaced pins into a standard breakout format that's easy to ...

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: SF-SEN-09405 | Brand: SparkFun

A simple-to-use MQ-6 gas sensor for detecting liquefied petroleum gas (LPG) — primarily propane and butane — in the air. The sensor detects concentrations from 200 to 10,000 ppm with high sensitivity and fast response...

SKU: SF-SEN-09404 | Brand: SparkFun

This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from ...

SKU: DF-SEN0375 | Brand: DFRobot

BME680 is a 4-in-1 multi-functional MEMS environmental sensor which integrates VOC (Volatile Organic Compounds) sensor, temperature sensor, humidity sensor and barometer. It is designed for air quality monitor, and du...

SKU: DF-SEN0233 | Brand: DFRobot

A multifunction air quality monitor that measures particulate matter (PM2.5), formaldehyde concentration, temperature, and humidity. It uses laser scattering to detect suspended particles in the air, an electrochemica...

SKU: DF-SEN0128 | Brand: DFRobot

An analogue alcohol gas sensor based on the MQ-3 probe, designed for use with Arduino and other microcontrollers. The sensor outputs a voltage proportional to the concentration of alcohol vapour in the surrounding air...

SKU: DF-SEN0678 | Brand: DFRobot

This Gravity air quality module uses Sensirion’s STCC4 gas sensing chip to directly measure carbon dioxide with the thermal conductivity measurement principle. It is designed for compact, cost-effective indoor monitor...
