Flow=(Average-68)*0.265+2.7; excuse me, i want to know how did you make this equation? thank you

I think it was a characterization of air flow spped and the voltage from the sensor, the he applied a linear regression and got the values. I don´t know if the linear behavior is the optimal modelling but is the easiest I guess.

I think there maybe something missing from this design. Standard LCD 16x2 displays do not have I2C capability they need an additional backpack. Please confirm?
