Hey guys i was wondering if you could help me out with my calculations.
I'm currently working on a project were we use an ultrasonic sensor to measure distance and later will convert to speed. the output from this is equal to 9.8 mV per inch.
We are using a 10bit AD-converter and we have chose to only read the 8 MSB. and now comes my problem: how do i calculate the output from the ADC to the actual distance?
my reference voltage is 2.5V
I really hope you can help me because i'm stuck(Brain freeze).
