arduino How to calculate Gas sensor PPM from analog ...

The sensors also require temperature and relative humidity compensation to adequately convert the output to PPM. To convert the sensor output to PPM you need to characterize the transducer by exposing it to known concentrations of the analyte, measure the output of the sensor at each concentration and develop a best fit algorithm.
