FSRs basically measure the resistance value (in ohms Ω) depending on how much is pressed. It is a changing resistor. FSR is made of 2 layers separated by a spacer. The harder one presses, the more semiconductors are contacted through these Active Element points, causing the resistance to decrease.
FSR sensor module, thin film in series It consists of pressure resistance and 10k ohm resistor, the greater the pressure in the sensing area, the higher the output voltage. The output will change even if you touch it with your fingers, and the induction is very sensitive.
