DEPARTMENT MANAGEMENT SYSTEM USING ARDUINO UNO.

DEPARTMENT MANAGEMENT SYSTEM                      USING ARDUINO UNO.

My latest Arduino DIY project is DEPARTMENT MANAGEMENT SYSTEM USING ARDUINO UNO.

The objective of this mini-project is to build a department management system .The management system includes a timetable, digital clock with temperature and a power saving module. This management system can be used in institutions such as Schools, Colleges, Universities, and Offices etc. It is even possible to store multiple timetables and switch between them. All of is achieved by integrating SENSORS and LCD to the ARDUINO MODULE. The proposed prototype system consists of a medium sized 20x8 LCD display, a 7 SEGMENT display, an LM35, a PIR sensor and an Array of Switches to switch between the days. All the device components are being powered by a 9V DC Supply adapter. In addition a DIGITAL THERMOMETER is also added to the digital timetable using LM35 module. A 4 digit 7 segment display shows the time. A PIR sensor connected with the Arduino checks for human presence and automatically saves power.
