· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated. MQ6 Gas Sensor ...

Here we see the different curves for each gas the MQ3 can detect in a loglog plot. Rs is the resistance of the sensor at target gas while R0 is the resistance of the sensor when only mg/L of alcohol is present in air. Determining RS/R0. We can use the fact (from the graph above) that the RS/R0 ratio is a constant 60 in clean air. Also, by ...
