FSR can be seen as a resistor, through the size of the pressure to change its resistance, the resistance (in ohms per unit Ω) depends on how much repression. These sensors are fairly low cost and easy to use, but they rarely accurate. They sort is various, performance difference is only about 10%.So basically you use FSR, you should prob…
