This sensor of approximately 8 centimeters makes it possible to measure weight or pressure in combination with the HX711 weighing sensor module. By placing a surface on it, a scale can be created, which can weigh an object up to 3 kg. This sensor works by bending with the pressure that is placed on it, which changes the resistance in this sensor.
