The MQ-3 sensor allows you to measure the concentration of alcohol vapors. The measuring range of the sensor is in the range of 0.05 mg / L to 10mg / L, and an analogue signal is obtained at the output.
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 MQ-6 sensor allows the measurement of LPG, propane and isobutane. The measuring range of the sensor is in the range of 300 - 10.000 ppm, while the output receives an analog signal.
The MQ-7 sensor allows you to measure the concentration of carbon monoxide (carbon monoxide). The measuring range of the sensor is in the range of 10 - 10,000 ppm
