Description
FSRs are basically a resistor that changes its resistive value (in ohms Ω) depending on how much it is pressed.  
The FSR is made of 2 layers separated by a spacer. The more on presses, the more of those Active Element dots touch the semiconductor and that makes the resistance go down.
FSR sensor module consists of thin film pressure resistor and 10k ohm resistor in series, the greater the pressure in the sensing area, the higher the output voltage. Even if you touch it the with your fingers, the output will change and induction is very sensitive.
Features:
- Working Voltage VCC: 5.5 VDC(MAX)
