Overview
The level of the Lake varies after rain storms. It would be nice to know how much, and to be able to review this information remotely. A Raspberry Pi and a depth sensor should allow this to work given a fixed sensor at a "Known" depth. The idea being to determine how much water is above the sensor at any given time.
The Raspberry Pi doesn't have an on-board ADC so an additional circuit is required to register voltage increases from sensors.
- This article discusses the different ways sensors can be connected to the Raspberry Pi.

Technology Behind Pressure Sensors
Possible Alternate Sensor Technology
- Optomax Digital Liquid Level Sensor - It's a Binary On/Off switch, but could be used to detect the simple presence of water at a given level in or below a building. IE: Has water reached the joists? Is water inside the cabin?
