FSR(Force sensing resistor)

news

FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost.FSRs are basically a resistor that changes its resistive value (in ohms Ω) depending on how much it is pressed. These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSRs you should only expect to get ranges of response.
