Abstract

Electronic scale is a very important measuring instrument. The electronic scale mainly uses the single chip microcomputer as the central control unit, uses the pressure sensor to measure the weight of the object, which will convert the pressure deformation caused by the weight of the object into the voltage value. Through the A / D acquisition circuit hx711, the A / D conversion is carried out, and the 24 bit binary digital converted is input into the high-performance single chip microcomputer for processing, and the final result is displayed on the display. With hx711, the In order to improve the accuracy of measurement.
