☑ Force Sensitive Resistor

The harder the force the lower the resistance. A force sensing resistor is a material whose resistance changes when a force pressure or mechanical stress is applied.

The fsr is made of 2 layers separated by a spacer.

Force sensitive resistor. The more one presses the more of those active element dots touch the semiconductor and that makes the resistance go down. As weve said the fsrs resistance changes as more pressure is applied. The harder the force the lower the resistance.

Force sensing resistor can be defined as a special type of resistor whose resistance can be varied by varying the force or pressure applied to it. Play media fsr usage. My interests are more in the unimaginative pure sciences.

This fsr will vary its resistance depending on how much pressure is being applied to the sensing area. The fsr sensor technology was invented patented by franklin eventoff in 1977. When no pressure is being applied to the fsr its resistance will be larger than 1mw.

This is a force sensitive resistor with a round 05 diameter sensing area. A force sensitive resistor is a type of variable resistor whose resistance decreases when the applied force increases. Arduino force sensing resistor fsr in this arduino force sensing resistor tutorial i will be going through all the steps to set up a circuit that can detect pressure placed on a pressure pad or commonly known as a force sensing resistor fsr.

This graph indicates approximately the resistance of the sensor at different force measurements. They are also known as force sensitive resistor and are sometimes referred to by the initialism fsr. Im not really the inventor type personality more of a system analyst type plus taking this particular instructable as an example i dont need a force sensitive resistor for anything even if other people might.

This is a force sensitive resistor with a square 175x15 sensing area. Analog voltage reading method the easiest way to measure a resistive sensor is to connect one end to power and the other to a pull down resistor to groundthen the point between the fixed pulldown resistor and the variable fsr resistor is connected to the analog input of a microcontroller such as an arduino shown. This fsr will vary its resistance depending on how much pressure is being applied to the sensing area.

The 12 diameter round part is the sensitive bit. When there is no pressure the sensor looks like an infinite resistor open circuit as the pressure increases the resistance goes down. When no pressure is being applied to the fsr its resistance will be larger than 1mw.

Force sensitive resistors are also known as force sensing resistors fsr force sensor or pressure sensor.
