Description of Half Bridge Strain Weighting Sensor Weight

★This module uses 24 high precision A/D converter chip hx711, specially designed for the high precision electronic scale. ★The load sensor is a group of half-bridge strain gauge, there are 3 ways to use it. ★Use one load sensor 50kg with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements. ★Use two weight sensor 50kg to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg. ★Use four weight scale 50kg to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg.

Compact Weighing Sensor: Perfect for Lab Experiments

I was hesitant about buying this sensor for my lab experiments, but I am so glad I did! My analysis of this product showed that it is small and lightweight but incredibly accurate. It is perfect for my weighing needs and I appreciate the industrial and SCIENTIFIC feel of this product. The only downside is that it requires some technical knowledge to install and calibrate properly. Overall, I highly recommend this product to educators and students alike. .

Pros
  • Accurate measurement of weight due to strain sensing technology.
Cons
  • Requires calibration before accurate measurement can be achieved.

Very accurate over a wide weight range. The software library is very mature.

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…

Pros
  • Delivery was very quick
Cons
  • Crumpled
