The principle of electronic scales:
When an object is placed on the weighing pan, the pressure is applied to the sensor, which deforms, thereby changing the impedance, and at the same time using the excitation voltage to change and output a changing analog signal. The signal is amplified and output by an amplifier circuit to an analog-to-digital converter. Converted into a digital signal for easy processing and output to the CPU operation control. The CPU outputs this result to the display based on keyboard commands and programs. Until this result is displayed.
