Background technique

Electronic scale is a kind of weighing instrument, which is a tool for measuring the mass of an object using Hooke's law or the principle of lever balance of force. According to the structural principle, it can be divided into three categories: mechanical scales, electronic scales, and electromechanical scales. When the object is placed on the weighing pan, pressure is applied to the sensor, which elastically deforms, so that the impedance changes, and at the same time, the excitation voltage changes, and a changing analog signal is output. The CPU outputs the result to the display according to the keyboard command and the program until the weighing result is displayed.

In the process of using the electronic scale, it is usually placed on the platform for weighing measurement. However, when the electronic scale is used outdoors, the bottom is mostly fixed, and the base cannot be adjusted.
