A new guide in the Adafruit Learning System! This one covers comparison of the MQ-3 vs. the MiCS5542 gas sensors. If you are looking for a practical guide as to how each of these sensors handles various gases (in a controlled but not absolute laboratory way), then this is what you should read. Save money and time on your next sensing project by reviewing this guide.
The testing is done with the ubiquitous Adafruit Circuit Playground Express and programmed in CircuitPython so wiring and code takes just a few minutes instead of hours.
