The 5 kg Load Cell Sensor is a strain gauge–based force measurement device designed to measure weight and load up to 5 kilograms with high accuracy. It converts applied force into a small electrical signal, which can be amplified and processed using modules like HX711. This sensor is widely used in digital weighing scales, force measurement systems, and embedded electronics projects.
