Hello everyone !
I have to built a coffee machine with a coffee tank (instant coffee) and a sugar tank. I'd like to measure a certain quantity of those grains.
First, I wanted to make a physical model to know the debit of the grains. But I noticed that it depends on many things like the shape of the tank or the diameter of the aperture compared to the average size of a grain. So I abandoned this idea.
I think that it could be possible to know a quantity of grains with a weight sensor. Let's say if we know the average mass of a grain, if we open the tank with a solenoid valve (I don't know if it's quite good for grains) and with the weight sensor when I reach the quantity I want I close the tank.
So that's my idea but I've a few questions. First, Is it the best way to do it ? If you've some ideas tell me them, please. Also are weight sensors damaged with water ( humidity in the air) ? And do you know a website where could I see and buy some references of weight sensors ?
Thanks in advance.
Regards :)
