Air Quality Sensor | MySensors Forum

· I copied one curve from the MQ2 datasheet : Along the horizontal axis you see the values 100, 1000 & 10000. Between 100 & 1000 each vertical line adds 100, between 1000 & 10000 each vertical line adds 1000. On the vertical axis it works just the same: each horizontal line between & 1 adds , between 1 & 10 it adds 1.

Analog Gas Sensor(MQ2) (SKU:SEN0127)

Analog Gas Sensor(MQ2) (SKU:SEN0127) Contents ... According to the datasheet for the MQ2, it is sensitive to 300-10000 PPM. A rough approximation would be the analog read value (79, 100, 67, ...) * (10000-300)/1024. Or, approximately analog read value * So given the values you reported, the estimated PPM of combustible gases is between 330 and 950 PPM. The Lower Explosive Limit (LEL) …

MQ-6 Gas Sensor Pinout, Specs, Equivalent, Circuit & Datasheet

· Basically we need to look into the (Rs/Ro) VS PPM graph given in the MQ-6 datasheet, and also shown below. The value of Ro is the value of resistance in fresh air and the value of Rs is the value of resistance in Gas concentration. First you should calibrate the sensor by finding the values of Ro in fresh air and then use that value to find Rs using the formulae: Once we calculate Rs and Ro we ...
