I would like to measure weight of 50 boxes from one Arduino. One box can be from 5 to 100 kg. Measuring precision of 0.1 or 0.2 kg is enough. Measuring interval is about 1hr, so speed or simultaneously reading is not issue.
What options for some cheap and simple sensors do I have?
Is there some I2C sensors available to use with Arduino?
Hopefully I should find something with low height profile so I don’t have to make modifications on existing boxes, something like this but with I2C: seeedstudio Load-Sensor-p-1344
This types give me more “mechanical headaches”, but if there is no other options I’l take this type also: phidgets
