Показать описание
An Arduino-based load cell scale and calibration procedure are given here.

A load cell is an application of strain measurements relating to weight measurement. A load is applied to a strain gauge, which causes the gauge to strain a certain amount and output a voltage proportional to the applied load. This relationship between strain and voltage is used in many applications where weight measurement is important. Load cells are very common because of their linearity, cost effectiveness, and their ease of implementation. In this tutorial, I will introduce an Arduino-compatible load cell that exemplifies all of the aforementioned advantages. I will also introduce calibration with known masses to create a powerful and accurate weighing system that can be used for highly accurate measurement purpose such as: chemistry, horticulture, cooking, and much more!
