It raises easily at 4095 if you release some gas nearby. In order to calibrate this sensor, having a look at datasheet and at arduino library (MQUnifiedsensor) is very useful. What I understand from datasheet is when sensor is in fresh air (condition of calibration), the ratio Rair/Ro...
The Grove - Gas Sensor(MQ2) module for Arduino is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, smoke and so on.
