By lady ada. Measure pressures from 0 to 22 pounds! They are basically a sensor that changes its resistance depending on the amount of pressure, force or stress applied to it. If any of these tutorial titles sound foreign to you, consider skimming through that content first. The harder you press on the sensor’s head, the lower the resistance between the two terminals drops. As more force is applied on the sensor, the resistance decreases. Force sensitive resistors are also known as force sensing resistors, FSR, force sensor, or pressure sensor. Any Arduino-compatible development platform -- be it a RedBoard, Pro or Pro Mini -- can substitute. For those soldering to the force sensitive resistor, you would need to solder at a lower temperature and ensure that the soldering iron is not heating the tab for no more than 1 second.

The WeMos D1 Mini is an inexpensive ESP8266-based WiFi board that is low-profile but just as powerful as any NodeMCU or ESP8266-based microcontroller. Then make sure to carefully apply force on the center from each corner (while avoiding the grooves on the side). The guide also presents a few more complex circuits you can try hooking up to get even more sensitivity out of your FSR. Force Sensing Resistor Testing. You don't want to overpower the maximum resistance of the FSR, but you also don't want the FSR's minimum resistance to be completely overshadowed either. To test, you can use a multimeter to determine if the sensor has a short or is able change in resistance. This kit comes with everything you need to hook your Force Sensing Resistor into your microcontroller or Phidgets Interface Kit.Connect the FSR to the voltage divider board using the 2-Pin female cable, or with the terminal adaptor.
