MQ6 MQ 6 MQ-6 Liquefied Petroleum isobutane-propane gas Sensor Module For Arduino. This sensor has high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC. The sensitive material of the MQ-6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to correspond output signal of gas concentration.MQ-6 gas sensor has a high sensitivity to Propane, Butane, and LPG, also a response to Natural gas. The sensor could be used to detect different combustible gas, especially Methane, which is with low cost and suitable for different applications.
