Where did the mgL = 0.67(val) come from? Do you have scientific background for it?

my LCD is Blank Blue. how can i fix this? and how to increase the sensitivity MQ3 sensor? please answer my questions I'll sub you.

@ohpetya 3 месяца назад

There is i2c module behind the lcd. You need to rotate variable resistor and configure it. The same thing you need to do with MQ-3.
