How does Arduino measure force?
In order to measure the applied force with an Arduino, you will need to build a voltage divider circuit with the FSR and a pull-down resistor. This circuit creates a variable voltage output that can be read by the ADC (analog to digital converter) input of the microcontroller.
How do you hook up a FSR?
FSRs are often a polymer with conductive material silk-screened on. That means they’re plastic and the connection tab is crimped on somewhat delicate material. The best way to connect to these is to simply plug them into a breadboard. or use a clamp-style connector like alligator clips, or a female header.

Where are force sensitive resistors used?
Sensitronics is the leader of The Force-Sensing Resistor (FSR) technology. Force Sensing Resistors can be used for such applications as computer input devices, musical instruments, medical instruments, robotics, automotive, interactive toys, sports and more.
Is force sensing resistor is analog sensor?
Analog Voltage Reading Method The easiest way to measure a resistive sensor is to connect one end to Power and the other to a pull-down resistor to ground. Then the point between the fixed pulldown resistor and the variable FSR resistor is connected to the analog input of a microcontroller such as an Arduino (shown).
What are the types of force sensors?
There are three main types: tensile force, compression force or tensile and compression force sensors. On top of that we provide force sensors with two or three measuring ranges as so-called multi-component sensors, or in a double bridge version (plausibility circuit).
