Interface level: 3.3 V (Compatible with 5V); Output signal Serial Port (UART) (TTL level 3.3V) --> i dont understand your claim it couldnt handle 5v rx tx levels; also a more in-depth explanation of the code would have been great; from my understanding there are two sources one could get the concentration from - pwm and uart but the calculated values of both arent the same in my case. Do you have similar experiences?
Thanks for makeing this vdo
May i ask , Can I use mh-z19 , mh-z19b , mh-z19d ro need to use mh-z19c only
Nice tutorial.
Where did you do this so nice presentation?
i used adobe sketchbook on my android tabled and recorded it. Thankyou for the comment. Sorry for the alte reply
You should make the font bigger on arduino ide its impossible to read. Good video though
