FSR402 Force Sensitive Resistor FSR
Original price was: ₨2,000.00.₨1,450.00Current price is: ₨1,450.00. Quick ViewThe FSR is made of 2 layers separated by a spacer. The more one presses, the more of those Active Element dots touch the semiconductor and that makes the resistance go down. 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 the sensor to sensor perhaps 10%. So basically when you use FSRs 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. However, for most touch-sensitive applications like “has this been squeezed or pushed and about how much” they’re a good deal for the money!
