How to Use MQ4 Methane Gas Sensor | Microcontroller …

2020911 · RS/R0 is the ratio of sensor resistance at target gas (RS) and resistance in clean air (R0). Hence, by knowing RS/R0, we can determine the concentration of the gas in PPM. We take two points on this graph to derive a formula. This formula will then be used in our Arduino sketch later on. The most obvious point is when RS/R0 = 1 and PPM = 1000.
