Arduino Force Sensing Resistor Setup

April 04, 2018

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. If you need more fsr related resources be sure to check out the integration guide.

How To Use A Force Sensitive Resistor With Arduino

In this tutorial you will learn how to use an fsr force sensitive resistor with arduino to fade an led.

Arduino force sensing resistor setup. We are using them in conjunction with an arduino to rotate a servo according to the amount of pressure. Now that youve got a force sensing arduino circuit what project are you going to create. These sensors are simple to set up and great for sensing pressure but they arent incredibly accurate.

They are pretty much used in diy electronics as they are available at low cost. In this instructable ill show you how to interface a. Next the bin was placed on a small and flat woodblock as a support between the bottom of the bin and the top of the base.

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. Interfacing force sensitive resistor to arduino. You might need to tweak this slightly for your own sensor.

How to use a force sensitive resistor arduino tutorial. The resistance changes by applying pressure on itlets get started. An fsrforce sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing.

Because the output voltage of the fsr is non linear i set up a custom range for each led to turn on. Force sensitive resistor hookup guide. In the experiment fsr was attached at the bottom of a small plastic bin with a piece of round shaped cardboard at the size of the sensor head to apply pressure directly to the force sensing resistor.

Arduino example code to control multiple leds with a force sensitive resistor fsr as pressure sensor. Fsr vs load cells. This sensor is a variable resistor just like a photocell or flex sensor.

A force resistive sensor changes its resistance based on the physical pressure or weight placed on it.
