Monitoring Water Level in a Tank

Let me get back with you after I receive all of the items

If you need the WIFI then go for the CC3200, it can do everything the 430 can do and way way more and has the benefit of the WIFI stack with little impact on flash space, the board is also much faster, not that you need that for your app but you will get the experience right away and this can become your goto board for many future projects

The 430 based boards are great too but for more local IO use, like all these level boards (Arduino’s included) they can rapidly run out of program space the minute you add IP networking and WIFI, regular radios etc as they typically use less program space . you will not have this issue with the CC3200

Thank you Peter.  I am willing to try any controller that can get this project done.  Like you said I have more projects to do if this ends up a success.

Thanks again

Works for me, codeable in C++, all I care about.  Things have come to a certain turn when we contemplate such horsepower for a dripper, but this is the era in which we find ourselves.

It is ever harder for me to adapt to the fact of how cheap computing has become.

Received the PSoC 4 Pioneer Kit

and just received the e-tape.  It has also a 0-5v VDC converter module

I have ordered the CC3200, just in case I run into issues during the programing process

Pictures are always good.  I would love to see the sensor in action.

Here is the e-tape in action

One way to dispense water is to have a container high up of it which is sealed at the top by a two-hole cork.  One tube has a solenoid that connects to the atmosphere.  It is a normally closed type.  It is normally under the suation of a controller, but it also has a push-button manual override. 

The other goes to a flexible tube which acts as a siphon.  Hold down the button and suck, pulling your tube over the reservoir.

The reason to do it this way, maybe, is that your solenoid is operating on air rather than water,  which can be easier.

If even head is important, you might want to suspend your reservoir on a spring.  I can't find the exact literature, but I know some people have had success in weighing stuff by putting their payload on a spring and treating the spring as an inductor.

Back in the days of working in the Oil Industry, I came across a level meter that used air.

The pressure required to release an air bubble(s) was used to determine the level in the tank.

Since it wasn't our device, I never did get all the details but it was safe for many types of liquid.

I've always thought it was clever because you can't loose product due to a fitting failure, and nothing sensitive is in contact with the product.

I recall experimenting with a similar system in early childhood. . .

That would be a fun system to reproduce.
