ABSTRACT

The project is based on the design and construction of a microcontroller 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 reset using an override switch.

A RESEARCH TOPIC ON ELECTRICAL AND ELECTRONICS

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.
