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

I am new to Arduino and electronics in am working on MQ 7 Gas sensor to test Carbon monoxide level. But the issue is i still can't grasp the concept of converting analog readings to PPM. I tried to follow this,but some parts, are very clear especially R0 = RS_air/(26+(1/3)) So far with my code below the ratio I get is between 20 and 30.

Connecting MQ2 Gas Sensor Module to Arduino UNO

May 28, 2021· MQ2 Gas Sensor? MQ2 is one of the popular and most used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of gas can be detected.

250+ TOP MCQs on MQ2 Gas Sensor Module and Answers

Calrification: The MQ2 Gas Sensor has two output pins, one is digital and one is analog. The analog pin’s voltage is set so that it is directly proportional to the PPM value in the air subject to variation in calibration from the potentiometer, so as the PPM level rises so does the voltage in the analog output pin until it reaches 5V.
