MQ Gas Sensors | Gas Sensors ? IoTbyHVM Bits …

Before we can use this formula in a sketch, we need to determine R0 of the MQ7 sensor first. This varies between devices so there is a need for actual testing. From the loglog plot, we can see that RS/R0 is constant in air and is equal to 1. Since by definition, R0 is the resistance of the sensor in clean air, then only RS varies for every gas. RS is the sensor resistance and forms a voltage ...
