Measuring PPM from MQ Gas Sensors using Arduino (MQ-137 ...

· The MQ gas sensors can either purchased as a module or just as a sensor alone. If your purpose is to measure only ppm then it’s best to buy the sensor alone since the module is good for only using the Digital pin. So if you have purchased the module already then you have to perform a small hack which will be discussed further. For now, let’s assume you have purchased the sensor. The pinout ...

How To Use MQ-135 Gas Sensor - Codrey Electronics

· You’re free to use the AO output of your MH-135 Chinese module as well, but you might need to change its load resistor to 10KΩ (or much better 22KΩ). While using the library-supported Arduino setup, MQ-135 gas sensor calibration is done at first by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL-1)x RL, that means Rs = (5V ...

BME688 first AI gas sensor Arduino how to -

· The gas sensor in the BM688 has a broad sensitivity and reacts to most volatile compounds as well as many other gases polluting indoor air. The intensity of the signal typically scales with the chemical reactivity of the gases. In contrast to sensors selective for one specific component, the BME688 is capable of measuring the sum of VOCs/contaminants in the surrounding air. This enables …
