  • My two cents worth:

    I did a multi-point calibration, with focus around 0.08BAC (for obvious reasons). With a 4.7k resistor (found it gave a good range) I found the following to be pretty accurate: BAC = (X/928)4.85 Where X is the analog voltage on an input pin on an Arudino Uno, sensor driven at 5V.


No public wish lists :(
