During the mid-1990s I was wondering how I could monitor the water level in my domestic water tank and display the readings neatly in my house. In 2010 I came across Microchip's PIC microcontrollers and found a project measuring temperature using an LM35 on YouTube, which was also sending its output to a computer via a serial port. This gave me the idea to use Ultrasound to measure the water level present in the tank and display the output on an LCD.

DisplayBox Secondary source code
This DisplayBox just receives the data and displays it on the 4 x 20 character LCD. Physically located in my mother's kitchen over the washing machine.
