NEW GUIDE: Comparison and Experimentation with Flammable Gas Sensors #MQ-3 #MiCS5524 #AdafruitLearningSystem #CircuitPlaygroundExpress #CircuitPython @adafruit

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.

Check out this new guide today!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
