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.
