A smart body fat scale combines the functions of a traditional scale with modern smart technology. It not only measures weight and estimates basic body composition data such as body fat percentage, but also provides a richer user experience and health management functions by connecting to smartphone apps, cloud services, or IoT platforms. Over time or under changing conditions, the internal sensors and electronic components may drift or age, affecting measurement accuracy and requiring regular calibration. However, existing body fat scales require professional calibration using specialized equipment, making them inconvenient to use. Summary of the Invention
