Load cell help.....

Using Arduino Sensors
1

Hey Guys, Im working on a project measuring the force output form electric outboard motors.
I have the possibility to use an SLS410 load cell, an opamp op90 and an arduino uno.

Is there anyone who has made an code for that allready? Im not the best code writher so I would really appreciate the help!!

A single OP90 is not enough. You need at least 2 (or 3) of them to make an instrumentation amp.
This is because you u'll need 'infinite' input-impedance.
There are 'out of the box' chips for this task: INAxxx / HX711

Thanx for the quick reply!!

just an other thing, I've forgotten how to make 2 coloms so I can integrate the mesuring results in an excel format.

Who understands this ?? not me.

Don't use an INA125P. HX711 modules are less expensive and far superior.

I assume you mean how to make a CSV output file that you can load into Excel?
