Introduction this is a quick how to explaining everything you need to get started using your flexiforce pressure sensor.
Flexiforce pressure sensor arduino code.
In depth code for analog fsr measurements this arduino sketch that assumes you have the fsr wired up as above with a 10k.
The resistance can be read by connecting a multimeter to the outer.
The code is very simple consists of a few lines.

When the force sensor is unloaded its resistance is very high.
This is what we have done.
Force sensing resistor circuit.
The same program will also run on the arduino mega arduino pro mini and arduino micro.
An fsr force sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing.
In this instructable i ll show you how to interface an fsr to arduino and change the brightness of an led depending on the pressure applied on the fsr.

This example uses the 25lb version but the concepts learned apply to all the flex sensors.
The circuit for this arduino project is super easy as we only need the force sensing resistor and a 100k.
When a force is applied to the sensor this resistance decreases.
Pull down resistor and the sensor is read on analog 0 pin.

For the flexiforce sensor interfacing watch my video tutorial available at the end.
The flexiforce single element force sensor acts as a force sensing resistor in an electrical circuit.
Force sensor resistor pressure pad 100k resistor.
The force sensitive resistor or fsr is connected with the analog pin a0 of the arduino.
Arduino uno or other arduino compatible board flexiforce pressure sensor breadboard m m jumper wires 1 megaohm.
They are pretty much used in diy electronics as they are available at low cost.
Has anyone had any success hooking up the flexiforce 100lb pressure sensor to the arduino.
Plus example circuits and arduino code to get you started.
We hooked up the the left pin to the 5v the middle pin to ground and the right pin to a0.
Flexiforce pressure sensor 100lbs.
This is the only setup that gives us a reading.
It is pretty advanced and will measure the approximate newton force measured by the fsr.
