Implementation of Automatic Door Opening System with Entry Counter for University Library

Automation is the technology by which a procedure or process is performed with minimal human assistance. This paper presents the implementation of automatic door opening system with entry counter for university library. It can be used not only for automatic door opening but also for counting entry person. It consists of entry unit and exit unit. Each unit consists of Arduino Uno, PIR Passive Infrared sensor and LCD Liquid Crystal Display . In entry unit, seven segment display is used as an entry counter to show the number of entry person. Welcome message and door condition are displayed on LCD. In exit unit, RTC Real Time Clock module shows a format of date and time on LCD. Quotes about library are also displayed on LCD.
