THE DESIGN AND CONSTRUCTION OF A MICRO-CONTROLLER BASED LIQUID LEVEL DETECTING SYSTEM

ABSTRACT

The project is based on the design and construction of a micro-controller based liquid level detector. This is a system that will measure the level of liquid in a container and display the level on 3 seven segment display screen. The system will output an audio and visual alerting indicator when the tank is full and when the tank is empty. This alarm can be re-set using an override switch.

This feat is achieved using a programmable integrated circuit that is programmed using assembly language as well as other integrated circuits such as a seven segment display driver, a multiplexer and logic gates. Also, I used other discrete components such as resistors, transistors, capacitors, diodes etc.

After the design, construction and implementation, the system functioned satisfactorily as a microcontroller based liquid level detector system with digital display readout.
