Hi all,
I am going to Interface 4 wire load cell to PIC 16F877A microcontroller.
range of load cell is 0-3kg,I do no have the voltage sensitivity of the loadcell,
planning to use 5V excitation voltage, as same source for microcontroller.
planning to measure 0-100g with 1g accuracy. how do i achieve this because ADC resolution of the PIC is only 5/1023 how do i disregard the other weights to focus on the 0-100g range? is there a snippet of C program that i can use to achieve this?
planinng to use built in ADC with 10bit.
instrumentation amplifier planing to use AD620,
Pls help me whether it will work as my requirements or not.
If it will not work pls suggest me new.
Thank you
