Simple self-made electronic scale

Abstract

The invention discloses a simple self-made electronic scale. The simple self-made electronic scale mainly comprises a display screen, a signal converter, an amplifier, a spring, a tray, a support, a slide rheostat, a power source, a switch and leads, wherein the display screen is connected with the signal converter, the amplifier is connected with the signal converter, the spring is connected with the support, the tray is placed on the support, a left end of the slide rheostat is connected with the support, the switch is connected with the slide rheostat, the switch is connected with the power source, and other parts are connected through the leads. The simple self-made electronic scale is made. When an object needs weighing, the switch is closed firstly; when no weight needs weighing, a resistance value of the slide rheostat is great, a current on the display screen is quite small, no number is displayed; when one weight is placed on the tray, under the action of pressure, the resistance value of the slide rheostat is changed, the current becomes greater, a number is displayed on the display screen; through a number change value on the display screen, mass of the weight can be conveniently known, not only can convenience and rapidness be realized, but also accuracy is high, and the simple self-made electronic scale is convenient for life of people.

Description

technical field [0001] The design of the present invention is an electronic scale, especially a simple and self-made electronic scale. Background technique [0002] With the development of society, people's living standards are constantly improving, and people's lifestyles are also changing. People hope that problems in life can be solved more quickly and work more efficiently. The status of electronic scales in life is getting higher and higher, and people need to use electronic scales everywhere in their lives, but the electronic scales on the market are not only cumbersome, but also have low accuracy, which often makes people complain. In order to adapt to the development of the market, I think it is necessary to invent a more accurate and convenient electronic scale, which can better solve life problems for people. Contents of the invention [0003] The problem to be solved by the present invention is to provide a simple and self-made electronic scale. Its production...
