Hi,
I am looking for a low cost weight sensor. I am trying to provide a
indication of the amount of paper available. The empty container is
approx. 1kg, and approx. 10kg full of paper. It should be able to
handle industrial temperature range. A resolution of 1kg would be
acceptable. If I can get 100g resolution, it would be great. I would prefer SPI or I2C interface, but analog out would be
acceptable - something that can directly interface with a MCU.
It looks like one of those problems that cost
$300 for a few or $.30 for 100k, but not a lot
in between.
Load cells would work, but will be quite expensive.
Springs, levers and opto or hall sensors would
be another possibility.
