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.
The module with a smoke sensor and flammable gases (MQ-2) allows the measurement of gas concentrations such as natural gas, hydrogen as well as smoke and ethanol. The module has an analogue output and an output triggered by exceeding the threshold of sensitivity. modMQ-2
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.
The SCD-40 CO2, temperature and humidity sensor module provides high accuracy readings. It is equipped with a Qwiic connector and communicates via an I2C interface. SparkFun SEN-22395
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.
