SparkFun Methane CNG Gas Sensor - MQ-4 Biometrics

SparkFun Methane CNG Gas Sensor - MQ-4 BiometricsThis is a simple to use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ 4 can detect natural gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensors 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
