This paper introduces the design and fabrication of a low-power and high-precision electronic scale with resistance strain gauge as the weight sensor. According to the demand of commercial measurement, the paper compares and proves the various design schemes, chooses the cantilever-type resistance strain sensor with the STC89C52 single chip, and uses the 24-bit high-precision A/D converter chip HX711 to convert the signal to A/D. The system has the advantages of high integration, fast response speed, high precision, low power consumption, and strong anti-interference, which lowers the cost and improves the performance and reliability of the whole machine.
