MQ-6 module, liquefied petroleum gas, isobutane, propane sensor, isobutane, propane detection

product description The sensitive material for the MQ-6 gas sensor is SnO2, which has lower conductivity in clean air. When the target combustible gas is present, the conductivity of the sensor is higher as the gas concentration increases. Use a simple circuit that converts the conductivity change to correspond to the gas concentration output signal. The MQ-6 gas sensor is sensitive to propane, butane and liquefied petroleum gas and also to natural gas. The sensor can be used to detect different combustible gases, especially methane, low cost, suitable for different applications.
