20160918· However, it is unlikely you are getting a PPM reading from the sensor unless you have calibrated the sensor and developed a function to convert voltage (or resistance) to a gas concentration. First of all, you typically need to calibrate the sensor by exposing it to a known concentration of the analyte (gas) and measuring the voltage / ADC reading. Second, those types of sensors usually have ...
