Interfacing MQ-2 Gas Sensor with evive - STEMpedia

MQ-2 Gas Sensor Sensitivity Characteristics: The graph tells us the concentration of a gas in part per million (ppm) according to the resistance ratio of the sensor (RS/R0). RS is the resistance of the sensor that changes depending on the concentration of gas. R0 is the resistance of the sensor at a known concentration without the presence of other gases, or in the fresh air. For air, RS/R0 ...
