The idea is to have and automated system to drain the water out of the "warning zone" out to another place, another idea is to harvest this water if you have the place to store some big containers.
Target: have a fully automated system that can measure the water level and in case the level is near the "warning" level, it activates a water pump to lower the level. As a secondary target the idea is to see the level in real time through a web page.
Bill Of Materials:
| Item | Pictures |

Phases for this project:
Phase 1: get the basic software working. Code the basics for the arduino to measure the distance and upon threshold, activate relay.
Phase 2: building the container for outdoors. Using an hermetic plastic container (a big tupperware :) ), fit all the parts in there, water proofing it, build the pvc tube with the sensor container.
Phase 3: initial testing, a data analysis.
Phase 4: attach wireless repeater in client mode, using network module to: monitor system from web, upload measurements information to mysql database.
