Measuring gas flow - Frequently-Asked Questions - Arduino ...

· Can anyone think of a way of measuring gas flow through a pipe non-invasively? I’m wondering if it’s possible to measure using ulrasound, possibly in the same way I’m planning to measure water flow (still can’t find suitable transducers) but my guess is that the level of accuracy and frequency of the ultrasound would have to be orders of magnitude higher than for a liquid. The only ...

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 ...
