How to use Force Sensitive Resistors (FSR) with Arduino - Simple Force Sensing Arduino Tutorial

In this video I will show you how easy it is to use Force Sensitive Resistors (FSR) to measure forces using an Arduino or other microcontroller with Analog Input. FSR's are relatively inexpensive and are great for simple projects where a rough measurement of force or weight is required. Unlike load cells, FSR 's can be used without an amplifier. They are easily interfaced with Arduino using an analog input channel.

thank you for that graph! I was litterally wanting to make a scale with it and this gave me great insights!

[julienegrandy]

Thanks so much, this was really helpful. I have a final arduino project due tomorrow morning, wish me luck!

This might just be the best youtube channel I've come across, not including RedBull/Drone Videos, Judo or Unbox Therapy

this is a great video! thank you so much. just what i needed :)

[ethanowen]

Very helpful guide, thank you! Do you have the spreadsheet you used for the resistance-weight calculations posted anywhere?

[DIYwithBatteries]

You've got cool stuff keep up the awesome content Sir 👍

[marcbenedict]

Thank you this helps a lot and easy to add more sensors with this logic

Awesome video and very helpful for a personal projet I'm working on! I was wondering if you have recommandations for stronger connection between the fsr and the rest of the circuits because my fsr placement is prone to sliding and shifting. Second, where did you find your weight column (first one on the excel) showed at 3:20? I'm using a 402UX and I'm working with heavier range of the pression and I'm still looking for the optimal resistance for my divider (any help will help :D). Thank you so much again to make quality content available!

I am looking for a mini size FSR board that can replace arduino board. Would you know which board I can use?

I am having two joyit sensors 0-2kg and 0-10kg. But I am not sure the values are correct. how do I calibrate it ? please tell me the procedure to calibrate the sensor and give me correct values

[rafalkhalid]

the last value of fsr represent force in newton ??

Hello, I want to measure the pressure in the sacral region of a bedridden patient weighing approximately 80-100 kg. Can I use this sensor?

[livnenir]

How does the resistance vs force graph look on a log-log / semilog scale?
Thanks for sharing:)

[Scienseism]

can I measure the impact force using this?.I want to build an impact analyzer. I want to measure real-time impact force due to cricket ball after hit the arm guard

[Ahmed-menu]

Thanks a lot for this amazing tutorial!

[otagophysio]

Hi Can I use this FSR for measuring upto 10- 200 KG. Please give the value of resistor to be used or the relevant video link. Thanks.

Do you need a finger or conductive contact for the sensor to work? I am thinking of putting these sensors on a robotic gripper I am building and it will be used for picking objects up. I got told that these resistors need a conductive material for it to work such as a finger? Is this true?

[vanduyphung]

Hi. Could you let me know what resitor use for FSR UX 400 sensor?

nice in a lab enviroment, any tips for how to protect this flimsy plastic in real usage

[FuryMuscles]

please sir I have a school task, and my project about teakwondo protectors with scoring systeme, and I want to use FSRs for detecting the applayed force but you said that it work only for light objects, so do you have any ideas, thanks for the video!
