Feather modules + FlexiForce pressure sensors

Post by kaicheng114 »

Hello,

I am a beginner at adafruit and feather.
I would like to know if it is feasible to connect adafruit feather module with the TekScan FlexiForce pressure sensors and display the pressure readings on a LED screen.
If yes, which modules I suppose to prepare, and do you have a tutorial on it?

Thank you.

Kai

Maybe? Those type sensors generally are all essentially just variable resistors. The information here might help:
https://learn.adafruit.com/force-sensitive-resistor-fsr
Not the exact same make/model, but might be useful info for reference.

Pretty much every Feather has analog inputs.

Also lot's of options for screens. Do you want a graphical display like a TFT or OLED? Or something simple like a segmented LED?

Hello adafruit_support_carter,

Thank you so much!
Regarding the screen, simple OLED Display is ok, but it will be fantastic if a screen can display the pressure values in a graph manner.

Can you provide me a list and links, regarding the items I need to buy to use the pressure sensor and get the pressure readings?
(the smaller the total assembly the better.)
BTW, can ADAFruit use Tekscan FlexiForce pressure sensors? coz they are have long length.

Thank you and I look forward to hearing from you.

We don't know for sure. But if the sensors are the same general "variable resistor" type, then it should be doable. It would just be a matter of reading an analog signal.

If you use the Feather form factor, then check out the various FeatherWing options for displays:
https://learn.adafruit.com/adafruit-fea ... play-wings
https://learn.adafruit.com/adafruit-fea ... play-wings

There may be newer options that the guide does not cover. So also look here for all options:

Thank you so so much !!!
Do you have a tutorial link regarding connecting Adafruit modules and pressure sensors and reading an analog signal?

Regarding the Tekscan FlexiForce pressure sensors, I saw a youtube video connecting it to an Arduino board.
If it can be connected to Arduino, it should also work with Adafruit modules, correct? :)

Seems like it should work then, assuming in the video they were using a generic analog input. That guide linked above for FSRs is a good generic reference.
