Is it possible to connect a load cell to a raspberry pi?

Question

I would like to make a rocket thrust stand. I want to do so by connecting a load cell to a raspberry pi for measuring the thrust that the rocket produces. Is this possible, and if so, would an Arduino be better for the job?

Answer 1

I think it is rather due to the performance of the sensor.

Answer 2

Can you link the load cell?
In industrial, usually the analog output is 4-20 ma.
With raspberry max analog input is 0.5 ma.

Answer 3

The rocket flies to sky so it has to include batteries for the Pi and sensors. I think it can carry multiple PSU for different equipment.
I don’t know about Arduino, but it seems more related to robot kind of things.
But seriously, you are not going to make an attack missile or something, are you?
If you are dreaming of KSP project, (just like your avatar), wouldn’t a flying droid will be more feasible? At least you want your rocket can return to ground safely, right?

FailSpace, "Don't try this at home."

Answer 5

Wong Hei Ming,

you’re right, although i do make sure to use all possible safety precautions, making sure not to cause fires or explosions. I make sure to use long burning fuses so that the rocket doesn’t ignite while next to me.

Answer 6

better to ask goggle

Answer 7

Wong Hei Ming,

It won’t be flying. I’ve decided to just have a computer-controlled thrust stand, which stays on the ground purely to measure the force output of the rocket. I won’t be using my rockets for anything dangerous to others. I will fly the rocket on an F class motor, and then install an ejection charge to return it by parachute.
