This is MQ-6 Gas Sensor ModuleSimple and easy-to-use device to detect LPG, propane, butane, and natural gas concentrations in the air.Sensitivity range from 200 to 10,000ppm.High sensitivity and fast response times.Output is an analog resistance, which can be easily connected to an ADC.Low-cost device suitable for a range of applications.Can be used as a digital or analog sensor and the sensitivity of the digital pin can be varied using the potentiometer.The MQ-6 gas sensor module is a simple and easy-to-use device designed to sense LPG, composed mainly of propane and butane, concentrations in the air. With a sensitivity range from 200 to 10,000ppm, the MQ-6 gas sensor is suitable for a range of applications.The MQ-6 gas sensor has high sensitivity and fast response times. The sensor’s output is an analog resistance, and the drive circuit is uncomplicated, requiring only a 5V power source to the heater coil, a load resistance, and a connection to an ADC.The MQ-6 gas sensor employs SnO2 as its sensitive material, which has low conductivity in clean air. As the concentration of target combustible gas increases, the sensor’s conductivity rises correspondingly. By using a simple electro circuit, the change in conductivity can be converted into a corresponding gas concentration output signal.
