    Hey all, new to this forum and looking for help finding something. I'm trying to locate a weight or force sensor that is sensitive enough to operate in the 0-10 gram range.
    Looking around at all the usual outlets for sensors and components I'm able to find a lot of stuff in the 100g to 1kg and even 1kg to 25kg range, but nothing as sensitive as what I require, and I'm not even sure what search terminology would actually turn up results, so I thought I would just ask other people if they knew of anything.

    If anyone could point me in a useful direction I'd be super grateful

    Yeah the problem I'm running into is finding one designed to operate in the 0-5 gram range, everything seems to have a lower bound of like 100g, for both load cells and more generic "force sensors"

    Thanks, I'll look into that. It doesn't have to cut off at exactly 5 grams or anything, it just needs to be able to provide tenths place accuracy in that range, for a kitchen gadget I'm cobbling together

    100 mg is no problem. I got a Scout from Ohaus several years ago. It gives 10 mg precision up to 200 g FS. Here is a more modern version: http://www.ebay.com/itm/OHAUS-SP202...200g-capacity-0-01g-readability-/271417632594

    That might be the cheapest way to get a load cell int he range you need.

    If you are in the US, buying a sensitive scale can present a few hurdles related to our "war on drugs." :( eBay may be a different story.

    Use strain gauge with a microcontroller circuit or visit www.edgefxkits.com for model number 185
