A weighing sensor is a device that can convert the weight of an object into an electrical signal, and it is widely used in various weighing and measurement systems. Weighing sensors are usually composed of elastic elements, resistance strain gauges, measurement circuits, and other components. When an object is placed on a weighing sensor, the elastic element will be subjected to pressure and deform, causing a change in the resistance of the strain gauge. This change is detected by the measurement circuit and converted into an electrical signal output, thereby achieving the measurement of the weight of the object. Weighing sensors can be divided into 8 categories based on conversion methods, including photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole transformation, vibration, gyroscope, and resistance strain gauges. Among them, resistance strain gauges are the most widely used
