Tanklevel provides an application for measurement of tank levels by hydrostatic pressure.
Internals
You need an aquarium air pump, some kind of pipe/tube, a Freescale MPX5050DP pressure sensor and an relay for the pump. Parameters are configurable by ECMD and stored in EEPROM.

Electrical setup
Electrical Setup is quite simple. Connect the TANK_PUMP port with an relay (usually via an Transistor as current amp) and the output of the Sensor with the selected ADC channel (have a look at the datasheet for power supply decoupling and output filtering). Select a optimal Vref for the ADC if possible.
