Gas Sensor Breakout Board

Module with an analog MQ6 propane sensor. It is powered with the voltage of 5 V and has an analog output. DFRobot SEN0131

A sensor that detects the concentration of nitrogen dioxide. Equipped with a factory calibrated probe. It communicates via the I2C interface, UART or analog output. DFRobot SEN0471

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 MQ5 LPG concentration sensor. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020056

Adapter for MQ gas sensor with potentiometer for analog signal calibration. MOD 72

The module with an alcohol sensor (MQ-3), allows you to measure the concentration of ethanol in the air. The module has an analogue output and an output triggered by exceeding the threshold of sensitivity.

Module with ozone detection sensor. It performs measurements up to 10 ppm with a resolution of 0.01 ppm. It has a UART output and an analog output. ZE25-O3

A sensor that detects the concentration of phosphine. Equipped with a factory calibrated probe. It communicates via the I2C interface, UART or analog output. DFRobot SEN0476

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.

Air quality sensor module based on the ENS160 system. It communicates via the I2C or SPI interface. DFRobot SEN0515

Module with a CO2 sensor based on the XENSIV PAS CO2 system from Infineon. It enables precise measurement of CO2 concentration in ppm via I2C, UART and PWM interfaces. SparkFun SEN-2295
