TīmeklisHow to Calibrate MQ9 Gas Sensor? Before using the module you have to calibrate it. This sensor measures the gas concentration based on resistance ratio. This ratio includes R0 (sensor resistance in 1000ppm concentration of LPG) and Rs (Internal resistance of the sensor which changes by gas concentration). Tīmeklis2024. gada 9. febr. · That’s it now that we have calculated the value of m and b we can equate the value of (Rs/Ro) to PPM using the below formula PPM = 10 ^ { [log (ratio) - b] / m} Program to calculate PPM using MQ sensor: The complete program to calculate PPM using a MQ sensor is given below. Few important lines are explained below.
