Re: Parallax and Maxbotix ultrasonic sensors

We used the Maxbotics EZ-1 last season using analog with good results.

The formula we used:
Mv =( (adc * 5000) / 1024 )
Inches = Mv / 10
Gave use the distance in inches for the version that used 10mV per inch.

It was changed from 10mV to 9.8mV
So in your case you might want to try:
Mv =( (adc * 5000) / 1024 )
Inches = Mv * 10 / 98
