Abstract

In this paper, handling the error in weighing signal is a very important topic. The load cell sensor produces the weighing signal. Sensor function is transforming the weight of things into a weak electrical signal. The noise from different sources like machines, electromagnetic fields, humidity, power lines and temperature variations produces errors in the weighing signal. As a result, the accuracy of the weight will be affected. The paper used hardware and software techniques to reduce the error in the weighing signal. The software filtering is used to reduce the unwanted effects. The average and standard deviation of the normal distribution signal are used to measure the error value.
