Lower power consumption is a godsend in this increasingly energy conscious world. Thus, a visitor counter is designed to save the usage of electrical energy and to avoid wastage. This project takes over the task of display counting the letters in the lette r - box precisely. When a letter enters the room, are the counter incremented by one .IR sensors are placed at the opening of letter - box and used to detect the presence of letter. The numbers of letters are displayed using a liquid crystal display. In this r eport, the project is introduced with a system block diagram followed by literature review that investigates the previous work done regarding the project. The methodology covers the technical explanations about the sensor circuits, main board and the signi ficant components of the project. Programming related software, flow chart and source codes are also elaborated for better understanding. The report continues with the results that show the completed circuit boards that able to function as designed. The pr oject achieved its aim and can be implemented in any letter - box to save energy and to provide an automated lifestyle.
