The MQ-5 Gas Sensor Module is a 32mm x 20mm x 22mm SnO2 semiconductor sensor with an analog interface, sensitive to H2, LPG, CH4, and CO gases, operating at 5V DC within -20°C to 40°C ambient temperature. Per the MQ-5 sensitivity curve, the mq5 gas sensor responds most strongly to LPG and hydrogen, with somewhat lower but still useful sensitivity to methane (CH4) and carbon monoxide (CO) — making this a broad combustible-gas detector rather than a CO-specific sensor like the MQ-9.
The lpg gas sensor analog interface outputs a voltage that rises as any of these gases’ concentration increases, read through Arduino’s analogRead() via a load resistor voltage divider — because the sensor responds to multiple gas types simultaneously, the analog reading represents combined gas presence rather than identifying which specific gas is detected. For applications needing to distinguish between gas types, the mq5 gas detector sensor reading would need to be combined with other sensors or environmental context. The mq 5 gas detector -20°C to 40°C range and 5V operation match standard Arduino project power and environmental requirements.
this mq 5 gas sensor module responds to multiple gases without distinguishing between them, it works best as a general “combustible gas present” alarm rather than for identifying specific gas leaks. Available from StemVolt, this MQ-5 gas sensor module is ideal for makers developing hydrogen, LPG, methane, and carbon monoxide detection systems, safety monitoring devices, and embedded gas sensing projects.
