Force Sensitive Resistor Square Sensor FSR 406

Force Sensitive Resistor FSR 406 is basically a resistor that changes its resistive value (in ohms Q) depending on how much it’s pressed. This force-sensing resistor is a fairly low cost, and easy to use but they’re rarely accurate. This FSR resistor also varies some from the sensor to sensor perhaps 10%. So basically when you use force sensitive resistor Arduino you should only expect to get ranges of response. While FSRs can detect weight, they’re a bad choice for detecting exactly how many pounds of weight are on them.
FSR square force-sensitive resistor is made of plastic and the connection tab is crimped on 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, female header, or a terminal block. This force pressure sensor resistor is possible to solder onto the tabs but you must be very fast because if your iron is not good quality or you dally even a few seconds, you will melt the plastic and ruin the FSR! Don’t attempt to solder directly to your FSR unless you are absolutely sure you have the skills to do so.
