HI, I cant not make sense of the wiring diagram if I compare it to a LM393 for the IC. Is a different OP-AMP iused? You can also mention that the anolog output is only +-0.5 and even the digital output only seems to vary from 0.2 to 1.2 volts, even if you drive the board with 5V. The analog and digital pins are inverted from each other.
