By combining the FSR with a static resistor to create a voltage divider, you can produce a variable voltage that can be read by a microcontroller's analog-to-digital converter. As more force is applied on the sensor, the resistance decreases. Force Sensing Resistor ® technology from Interlink Electronics is the most versatile force-sensing technology on the market today—and we should know. Now that you've got a force-sensing Arduino circuit, what project are you going to create? It helps to know what range of force you'll be reading. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. If your project's force-sensing covers the broad range of the FSR (e.g. I used a 10 kΩ pull-down resistor and a Vcc of 5 V for this tutorial, which results in the following output when no force is applied: They are simple to use and low cost. The force sensitive resistor will be easier to clamp down compared to the other flexible substrates on the flex sensor and SoftPot.
