Review on Half Bridge Strain Weighting Sensor Weight by John Swain

Very accurate over a wide weight range. I mounted four sensors on a three quarter inch thick piece of plywood. Be sure to drill a second hole under the first notch to allow the center of the load cell to deflect. Once connected, I was able to measure objects ranging in weight from 13g to 180lbs. In my house nothing was heavier than me, otherwise I would have weighed it. The hx711 library is well documented and easy to find on GitHub. It's also a very well written library for Arduino, esp8266/32.
