An FSR is a great sensor, which is easy to implement. It is
very similar to a potentiometer (CIRC-08), except rather
than varying its resistance in relation to shaft position its
resistance varies with pressure. The resistance is high (infinite)
when there is no pressure and low when the pressure is high (~250 Ohm with ~10 kg
force). Beyond that the implementation is pretty simple. If you’d like to delve a little
deeper more detail can be found online.
