connect weight sensors to raspberry pi - Raspberry Pi Forums

-

i'm cs background. need connect weight sensors raspberry pi , record readings. required apart strain guage , analog digital converter. please help. , let me know how connections.

1) google "reading weight sensors", "reading strain gauges"

2) high-resolution adc, 16 bits

3) differential op-amp circuits

4) "excitation voltage", "common mode voltage"

5) if excite 5v, can run adc @ 5v , share ground pi

6) better have isolated ground strain gauge, makes circuit more complicated

once collect information above, have sample schematics , sample code can adapt purposes.

watch out common mode voltage differentials frying adc/pi if don't handle them properly.
