Frozenbeernuts 1,652 Posted January 17, 2017 I know some of you have good technical backgrounds. I am very new to this type of stuff but am trying to learn. Searching for the right hardware is difficult because I am not quite sure what I am looking for or what the technical verbiage means. Anyway, I am looking for a very small strain Guage, maybe 5mm x 5mm maximum. Something that is water proof. I want it to be accurate to the hundredth of an ounce or tenth of a mL. I want it to be able to measure the weight of fluid on top of it basically. Getting even more technical, I want to be able to transmit this data via Bluetooth. So as far as I know I need a strain Guage, a micro Bluetooth chip, and a power source (battery). Do I also need a microcontroller? Share this post Link to post Share on other sites

tanatastic 2,061 Posted January 17, 2017 I use my bunghole to gauge strain. If it bleeds, I pushed too hard. Share this post Link to post Share on other sites

Mookz 1,287 Posted January 17, 2017 I use my bunghole to gauge strain. If it bleeds, I pushed too hard. Took the words right out of my butt. I was thinking hemorrhoid size. Share this post Link to post Share on other sites
Frozenbeernuts 1,652 Posted January 17, 2017 https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=waterproof+strain+gauge Thanks. Never thought to include waterproof in the search. This has better results than just searching for strain gauges. Share this post Link to post Share on other sites

Frozenbeernuts 1,652 Posted January 18, 2017 Ok so I think I have found what I am looking for, and it is not a strain gauge. I am looking for a Load Cell, which can contain Strain Gauges if on a larger scale. So I found a nice cheap Load Cell with a Load Cell AD Module (this one includes an amplifier if I read it correctly) included for less than $5. Now I need to get the microcontroller, probably an Arduino Uno, and I need to figure out how much battery I need to supply all this with power. Since I never paid attention to electricity and what all the measurements mean, I am going to have to start learning. Share this post Link to post Share on other sites
drobeski 3,061 Posted January 18, 2017 Ahhhh ...a load cell. Easy Now you need a battery operated weight transmitter. Check out Mettler Toledo they specialize in weighing intruments, load cells and transmitters. http://www.mt.com/us/en/home.html Share this post Link to post Share on other sites
