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?
