Water tank level meter
======================

This is an Arduino project that uses an LV-MaxSonar-EZ4 MB1040 ultrasonic rangefinder to measure water level.  The signal goes to an Arduino Uno and information is transmitted via a WRL-10535 RF Link Transmitter (315MHz).  An RF receiver listens to the signal and displays the level on an LCD-09351 Serial Graphic LCD (128x64).

The physical configuration is:
