i have the load cell of 100kg i have a ADC NAU7802. i have to calculate weight through this ADC. can anyone have idea how to convert ADC value to weight.
gain =128 excitation=4.5 v 24 bit adc so 2^24 -1=16777215;
//convert adc value into volt volt=(((float)present_adcdata*excitation)/((float)16777215*gain)); volt=present_adcdata*.000002095; // i get in mili volt 128 gain
load cell capacity is 100kg load cell sensitivity=2mv/v excitation=4.5 v
100kg -> 9mv
1:100,00 = x *9 mv
x= 9/100,000
x=0.00009 1 gram want 0.00009 mv
not convert adc volt into gram
gram=volt/0.00009;
is my calculation is right or wrong
