hi guys first the anwser kai as to why don't i want to use the idea andy gave me. the reason is i can not get that part where i live.The reason i think i need a lower resolution adc using a wheatstone bridge is because the test circuit i made up which gave me an ouput of 800.0mV and with the resistor in the bridge which was 200 ohms with those values i could put it in the formula to calculate the unknown resistance which allowed me to be able to measure 0.01 change resistance for only change of .1mv change in the output so to get which would only require 100uV per bit resolution as to 10uV per bit |
