Scale program

Projects Programming

Sorry to bother you, I'm currently doing a project for my last year of high school and I'm blocking..
My project is to create a scale
I have
https://www.gotronic.fr/art-interface-1046-pour-4-capteurs-de-force-17603.htm

I created the system to be able to exert a force on the sensor with aluminum and wood. The person will climb on the wooden board that rests on the aluminum rod that is placed on the sensor.
My problem is I can't do my program.
How to go from a force to a mass...
thanks in advance

How to go from a force to a mass..

Force is mass times acceleration.

yes
F=mass* g
with g=9.81 m/s^2

so I have to divide the value by 9.81.
that's it?

You have to calibrate your sensor in any case, so just hang various masses from it and record the reading.

Work out a scale factor and offset, following this tutorial: Why Calibrate? | Calibrating Sensors | Adafruit Learning System.
