Water tank project
Like many people on rural property, we get our water from above :-).
It is commonly known that, if you want to have a shower and shave it does not rain hence, a water tank is important, if you want to have water on demand.
On my property we have a water tank in the ground, it has a big concrete lid on it and for this reason it is hard to check the water. So.... time for a new gadget.
The objectives.
- Determine the level of water in an underground water tank.
- Log the water level to my server so I can check when we need a "top-up"
- Identify how much water from rainfall actually reaches the tank. (after first flush etc).
How it should work

Result
Challenges
- Getting the unit talking to the home server
- Coding a bit of software (thanks "Niko") to collect the poling results and to store them in a file.

End result
