Please note, however, that the actual force applied to the resistor depends heavily on the particular implementation and the tolerance of the specific FSR you're using. In order to determine an actual weight, it is recommended that you calibrate the sensor with a known force in order to form an empirical force/resistance curve. Otherwise, this sensor is great for detecting things like weight shift and relative force.
