In this video I'm going to tell you what load cells are and how they use a resistor that varies its value depending on the deformation (strain gauge) to allow us to measure weights in industry and at home. In addition to seeing how they are manufactured and how they are connected, we are going to learn how to read their technical characteristics and calculate a simple circuit to send that measured magnitude to a display or a microcontroller (Arduino, or whatever) Calculator app: https://play.google.com/store/apps/de...
