Fermion: MEMS Ammonia NH3 Gas Detection Sensor - module with ammonia sensor

Module with LPG gas concentration sensor (MQ-6) in the range of 200 - 10,000 ppm. The module has an analogue output and a digital output triggered by exceeding the threshold of sensitivity. modMQ-6

Module with an analog gas sensor. It allows you to measure the concentration of NO, NO2 and H2. DFRobot SEN0441

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.

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 four gas sensors that allow the detection of CO, NO2, alcohol and volatile organic compounds (VOC). The board is equipped with a Grove connector and communicates via the I2C interface. Seeed Studio 101020820

A sensor that detects the concentration of hydrogen. Equipped with a factory calibrated probe. It communicates via the I2C interface, UART or analog output. DFRobot SEN0473

The module with a methane concentration sensor (MQ-4) in the range up to 10,000 ppm, has an analogue output and an output triggered by exceeding the threshold of sensitivity.

A sensor used to detect air pollutants by measuring VOCs and gases such as ammonia or hydrogen sulfide. It is used in various areas, such as the food industry, chemical industry, air quality control in laboratories and environmental monitoring. Figaro TGS2602

Module with a knock-on sensor for measurement of methane, propane and carbon monoxide (MQ-9) concentrations. 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
