☑ Make Force Sensitive Resistor

There are several resistive based sensors but force sensing resistors operate satisfactorily in difficult environments and also requires a simple interface compared to other resistive based sensors. This graph indicates approximately the resistance of the sensor at different force measurements.

How To Use A Force Sensitive Resistor With Arduino

The way this works is that as the resistance of the fsr decreases the total resistance of the fsr and the pulldown resistor decreases from about 100kohm to 10kohm.

Make force sensitive resistor. Play media fsr usage. A force sensing resistor is a material whose resistance changes when a force pressure or mechanical stress is applied. In this configuration the analog voltage reading ranges from 0v ground to about 5v or about the same as the power supply voltage.

How to use a force sensitive resistor arduino tutorial. In this tutorial you will learn how to use an fsr force sensitive resistor with arduino to fade an led. As weve said the fsrs resistance changes as more pressure is applied.

They are also known as force sensitive resistor and are sometimes referred to by the initialism fsr. When there is no pressure the sensor looks like an infinite resistor open circuit as the pressure increases the resistance goes down. The resistance changes by applying pressure on itlets get started.

This sensor is a variable resistor just like a photocell or flex sensor. Force sensor resistor fsr this resistor is the most important part of the circuit as it will detect whenever pressure is applied to the flat area of the sensor. If force is applied to a surface of sensing film then the particles touches the conducting electrodes and thus resistance of the film changes.

Make a force sensitive resistor a pressure sensor with spare parts instead of spending 5 20 each. The fsr is made of 2 layers separated by a spacer. The 12 diameter round part is the sensitive bit.

For this tutorial i make use of a flexiforce pressure pad sensor but there are a lot cheaper alternatives including making your own. The more one presses the more of those active element dots touch the semiconductor and that makes the resistance go down. Force sensing resistor layers.
