I will post which IC i used and how well it works (if i get it to work
)
right now I have ordered another IC ..the number of which I dont remember off the top of my head, but it was not QTxxx it was some other IC i found online...
About designing circuit not really, the project we proposed was an alcohol/beverage dispenser. We have succesfully tested our software and simple hardware to dispense (using solenoids to open and close vacuum lines going into the bottle.)
So one important part of the project is to have a warning/prompt/alert or something on the software screen that can say bottle cannot be dispensed because it is empty.
If no such feedback is made, then the software operator will not know if drink was actually dispensed or not (and the software soft counters would be misleading because there would be no actual dispensing).
The project was our own proposal, so we can flex on using any type of setup/software/ics etc.
As i stated above right now we are making it so that original alcohol bottle can be used by only placing our cap. If however the empty sensor gives us too much trouble we might just go ahead and buy big square empty tanks and drill the level sensors (like float sensors) in it. Or use infra sensor as we would know what value will be received if its empty.
hopefully we can find some solution to do it without changing our whole idea.
project is due around first week of May 06
Thanks for the support.
I am also looking at QT-301 chip incase our current one does not work.
