5. Portable electronic scales

When an object is hung on the hook of the tensiometer, pressure acts on the sensor, which deforms and changes the positive reactance. At the same time, the excitation voltage changes, and the changed analog signal is output, which is amplified by the amplifier circuit and then output to the analog-to-digital converter. It is converted into a digital signal which is convenient for processing and output to the CPU for operation control. The CPU outputs the results to the display according to keyboard commands and programs until the results are displayed.
