MQ3 alcohol sensor Arduino code | Step by step ...

May 27, 2021· The tin dioxide-coated sensing element (we talked about above) absorbs oxygen to the surface when heated to a high temperature. When fresh air enters the sensor, electrons are attracted to oxygen molecules from the tin dioxide zone. Then a layer of electron decay forms below the tin dioxide particles. Also, a potential barrier is created.

Senso - Arduino Project Hub

I will be using the Arduino MKR Fox for this project. I have previously used it in a bunch of projects that rely on low-power communication due to its great low-power functionalities. It is very easy to use SigFox on this device as it is built in and Arduino libraries allow you to get up and running in no time.
