Hi, i'm looking for a load cell that can detect .5 grams. My project is a scale that senses when our small parrot poops on it and dispenses a treat. We plan to have the "toilet" ring that the parrot flies to seperate from the scale they poop on so that it doesnt trigger the sensor.
My internet says milligram load cells can be purchased for between USD500.00 and USD1,000.00.
Thank you, do you have any links where I purchase 1? This sensor doesn't need to be accurate, in the sense, I just need it to be able to detect that roughly .5 or more has been dropped on it.
Search: milligram load cell
Buy one of these (US$25), remove the load cell, and connect the cell to an HX711.
Search for TA221 and have a look at this detailed project Open-Source Digitally Replicable Lab-Grade Scales
These are what I use https://amz.run/9mZQ
Look for "100gram load cell" on the big sites.
That, and a HX711 board.
Leo..
Thank you! We ordered some load cell, but they may not work for us. We will plan to take the load cell from the pre existing scale you provided the link for if our load cells don't work.
