Hazardous Gas Monitor

Once you have the sensor voltage, you can convert that into a parts per million ("PPM") reading using the sensitivity calibration curve on page 5 of the gas sensor datasheets. To do this, recreate the sensitivity curve by picking data points from the graph or using a graphical analysis software like Engauge Digitizer. Plot PPM on the yaxis and V_RL on the xaxis, where V_RL is the sensor ...


Gas Detection and PPM Measurement using PIC ...

20200324· The MQ6 sensor is used to detect LPG gas concentration. Therefore, the MQ6 sensor will provide a particular resistance during the clean air condition where the LPG gas is unavailable. Also, the resistance will change whenever the LPG gas is detected by the MQ6 sensor. So, we need to plot this graph into our firmware similar to what we did in our Arduino Gas detector Project. The formula is to ...
